Is there any reason why we have this funny
lib-src/fns-<version>.el
plus
symbol-file-load-history-loaded
plus some code to write/read the load-history to/from that file ?
Why not do
(setq load-history (copy-sequence (purecopy load-history)))
at the end of loadup.el so that the history is (mostly) in purespace.
That seems both simpler and more efficient (in my case at least fns-*.el
is pretty much always loaded anyway, but with the current scheme it's not
in pure space).
Stefan
PS: the `copy-sequence' is because the spine of load-history is
destructively modified with setcar/setcdr when re-loading a file.

For most users, fns-*.el is not normally loaded.
Therefore, the current handling is better.

Is that really true ?
eval-after-load loads it and so does C-h f or C-h k, so I would
expect that it does get loaded very often.

Why is it better ?
Putting it into pure space would be more efficient when fns-* is loaded
and would not be noticeably worse when it is not loaded (since it's
mmap'd on demand from the `emacs' executable).
Also it's more complex, with special code in subr.el and loadup.el
to handle it. And it's not quite correct either. Try:
emacs -q --no-site-file
M-x load-library RET simple RET
C-h f when RET
and you have now a load-history where "simple" appears twice, whereas
if you had done the C-h f before the load-library you'd have ended
up (correctly) with a single entry for "simple".
