It's an obscure internal detail that is of no interest neither to
users nor to Lisp programmers.

In general, any cache is introduced to speed up certain frequent
operations by eliminating the need for recomputing something
expensive; I'm sure you know that already, as do most programmers.
Why a cache is needed in this particular case and how it is managed,
are issues that no one except redisplay hackers should care about.
IMHO, of course.
