The reported problem is that `char-displayable-p' takes too long to run
the first time it is called after starting a fresh Emacs.
The recipe is:
0. emacs -Q
1. (benchmark-run 1 (char-displayable-p ?\u25B7))
(The above takes 200ms here.)
Is this something we will want to do something about or is this all
working as expected? The discussion in the bug report suggests that
this is indeed something that we can live with.
