[ELPA] New package: gcmh-mode

[ELPA] New package: gcmh-mode

[Andrea Corallo via Emacs development discussions.]

Hi all,

I'd like to propose GCMH as GNU Elpa package.

It enforces a sneaky Garbage Collection strategy to minimize GC
interference with user activity.

During normal use a high GC threshold is set.  When idling GC is
triggered and a low threshold is set.  The intent is to do as much GC
activity as possible when the user is not interacting with Emacs.

<https://gitlab.com/koral/gcmh>
<http://akrl.sdf.org/#orgc9536b4>

I've "recently" implemented Stefan's idea to compute the idle timer time
based on the last garbage collection time.

The package is on MELPA since ~2 years with I think a decent number of
(I assume happy) users.

Blaming current master I believe the other two contributors are below 10
contributed lines so I think should be copyright assignment wise okay.

Feedback welcome.

Thanks

  Andrea

I have tried it, enabled it, and watched on side. Then I came back and could find Emacs swapping or doing something with memory that I could not interrupt it or see what is going on.

I had to killall emacs

You may want to tweak `gcmh-high-cons-threshold' and `gcmh-idle-delay'
depending on your needs and machine you are on.

That said if you need some help please provide more details filing a bug
report, otherwise is difficult to understand what's the cause.  This
kind of generic messages are of little help into progressing with
issues.

I would be very specific if I would know what specifics you need and
how I can obtain it.

All specific details I have is that I just loaded the library and
turned on the mode without customizations.

How do I get information what is the need of the machine to tweak it?
I have 4 GB and 8 GB swap. There are other 4-5 different computers
too, some have 8 GB and 8 GB swap.

Regarding specific reporting, I would if I could as I say. When
something is turned on and I have to abort process sadly I have no
other information at hand. That is why I mentioned as maybe you know
better how to provide you specific report on that. It means when I
cannot give you specifics your feedback is useful.
