TODO: check that pulling still works and that
"./pre-inst-env guix lint --checker=derivation" doesn't report porblems.

* Various number comparisons

(All the performance numbers below are for a SSD, on a HDD I would expect
the differences to be more pronounced.)

The number of modules indirectly used by the Guix package is reduced from

$ guix graph --type=module guix | grep -F 'label' | wc --lines
> 347

to

$ ./pre-inst-envguix graph --type=module guix | grep -F 'label' | wc --lines
> 172

(Note: you will have to patch source-module-closure first to ignore #:autoload.)

I.e., it is reduced by about half!

Memory usage and time spent in GC, before and after the patch (run thrice).
Before:

$ GUIX_PROFILING=gc guix build -d -e '(@ (gnu packages package-management) guix)' --no-grafts
Garbage collection statistics:
  heap size:        72.46 MiB
  allocated:        184.59 MiB
  GC times:         15
  time spent in GC: 1.04 seconds (56% of user time)
Garbage collection statistics:
  heap size:        72.52 MiB
  allocated:        184.60 MiB
  GC times:         15
  time spent in GC: 1.11 seconds (58% of user time)
Garbage collection statistics:
  heap size:        72.46 MiB
  allocated:        184.59 MiB
  GC times:         15
  time spent in GC: 1.05 seconds (57% of user time)

After:
$ GUIX_PROFILING=gc ./pre-inst-env guix build -d -e '(@ (gnu packages package-management) guix)' --no-grafts
Garbage collection statistics:
  heap size:        46.95 MiB
  allocated:        174.24 MiB
  GC times:         17
  time spent in GC: 0.88 seconds (55% of user time)
Garbage collection statistics:
  heap size:        46.95 MiB
  allocated:        174.24 MiB
  GC times:         17
  time spent in GC: 0.88 seconds (54% of user time)
Garbage collection statistics:
  heap size:        46.95 MiB
  allocated:        174.23 MiB
  GC times:         17
  time spent in GC: 0.88 seconds (55% of user time)

The heap size is lower: 72.50 MiB -> 45.95 MiB.
Don't know what's up with the GC here, but the percentage didn't increase,
so doesn't seem bad to me.

Now, start-up latency.
First, do

$ echo powersave | sudo tee /sys/devices/system/cpu/cpufreq/policy*/scaling_governor

to avoid the OS from interfering by making the CPU faster.

Before:

$ guix shell hyperfine -- hyperfine -w2 -- "guix build -d -e '(@ (gnu packages package-management) guix)' --no-grafts"
  Time (mean ± σ):      4.137 s ±  0.017 s    [User: 5.516 s, System: 0.270 s]
  Range (min … max):    4.108 s …  4.160 s    10 runs

After:

$ guix shell hyperfine -- hyperfine -w2 -- "./pre-inst-env guix build -d -e '(@ (gnu packages package-management) guix)' --no-grafts"
  Time (mean ± σ):      3.830 s ±  0.038 s    [User: 4.976 s, System: 0.241 s]
  Range (min … max):    3.794 s …  3.922 s    10 runs

-- a small but measurable improvement.  This was with warm disk caches, what about cold
disk caches?  As the number of loaded modules is reduced, the number of 'read from disk<->Guile determines
what to read next' roundtrips decreases, which should make things faster (especially on spinning disks).

Before:
$ guix shell hyperfine -- hyperfine --prepare='sync; echo 3 |sudo tee /proc/sys/vm/drop_caches' -w2 -- "guix build -d -e '(@ (gnu packages package-management) guix)' --no-grafts"
Benchmark #1: guix build -d -e '(@ (gnu packages package-management) guix)' --no-grafts
  Time (mean ± σ):      5.146 s ±  0.072 s    [User: 5.647 s, System: 0.442 s]
  Range (min … max):    5.072 s …  5.274 s    10 runs

After:
guix shell hyperfine -- hyperfine --prepare='sync; echo 3 |sudo tee /proc/sys/vm/drop_caches' -w2 -- "./pre-inst-env guix build -d -e '(@ (gnu packages package-management) guix)' --no-grafts"
Benchmark #1: ./pre-inst-env guix build -d -e '(@ (gnu packages package-management) guix)' --no-grafts
  Time (mean ± σ):      4.536 s ±  0.032 s    [User: 4.924 s, System: 0.329 s]
  Range (min … max):    4.480 s …  4.577 s    10 runs

Again, an improvement.

Let's look at the number of syscalls this time.  I don't know what's up with the symlinks.

Before:
$ guix shell strace -- strace -c guix build -e '(@ (gnu packages package-management) guix)' -d --no-grafts

'mmap' is called less, I don't know how much of that can be attributed
to less .go files being mmapped and how much to the lower memory usage.
I'd assume that the reduction in 'openat' uses (1024->847) is due to
less modules (and maybe as a consequence, less patch files?).

* Other information

There were a few things unclear with the performance numbers above, but I
think I can state that this patch series does, in fact, reduce memory usage
(CPU time and heap size for computing "guix build -d guix --no-grafts"),
albeit less than I hoped for.

The same methods can be applied for other packages as well -- maybe in the
future, we could simply do an #:autoload for _every_ imported package module.

The latest commit was a bit ad-hoc, to save time making this patch series.
I would expcet that, with some additional work, more modules can be removed
from the graph.
