Does setting inhibit-compacting-font-caches non-nil changes anything

Unfortunately, I can no longer run the same test, as this morning I changed my desktop configuration drastically (to fix a graphics driver freeze -- not an Emacs bug) and I now get quite-different performance results. It's a real hassle to change the configuration (it's easy to mess up and be left with a complete reinstall as the only real alternative) and I'd rather not go back, sorry.

In my new configuration I get different results. If I run:

emacs -Q -eval "(describe-variable 'password-word-equivalents)"

and immediately type C-x C-c to exit, gprof reports the following hot spots. Although it is a bit discouraging that so much garbage collection is occurring in such a simple use of Emacs, I suspect this is not Drew's problem.

If some of the characters there end up being displayed as squares with
hex codepoints, i.e. you have no fonts capable of displaying them,
then this is expected.

The characters are all displayable. I see no squares.

We should move password-word-equivalents to an i18n-related file anyway
(that is, regardless of Drew's problem), as password-word-equivalents
doesn't belong in simple.el.
That's a separate issue, and will just move the problem from one file
to another.

Yes, of course.
