Oh, yes, I forgot.  There is image-cache-eviction-delay as well.  If you
set this to a sufficiently small number, the test frees the pixmaps as
required.

Is there a specific reason you are interested in this problem?  It's
possible that we need to improve the conditions under which the image
cache is freed, but it's hard to tell unless we have a use-case in mind.
(Obviously, the current system assumes that the rate at which images are
created is much lower than the "usual editing speed".)
