Any version after 24.5 (e.g. 25-27).

In the past I was getting a lot of crashes in the same context,
but it seems that some bugs related to fonts got fixed or something.

The problem is apparently just that I have a lot of installed
fonts etc. and simple.el now contains chars that make the
font-search take a long time with a lot of fonts (or perhaps
with particular fonts, as for `char-displayable-p').

I (and others, AFAIK) see such slowdowns due to font stuff.
We've been through this many times, with Eli generally pointing
out what the problem is (fonts).  AFAIK, there's nothing to be
done here, apart from uninstalling fonts.

But, since you asked, there still is at least bug #30539,
which I would like to see fixed if possible.

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=30539

I can work around that bug by setting variable
`inhibit-compacting-font-caches' to t.  But even if it is t
it takes 2.5 minutes or so for simple.el to show its text.

Anyway, besides my font-related slowdown, which I can live
with, `simple.el' is pretty large.  I thought perhaps it was
time anyway to split some of it off.  If not, so be it -
just a suggestion.  Does everything there belong there?
