When you close the diskfont, or close a library, or close a device (and perhaps
more resources as well), they are marked as EXPUNGABLE but they aren't
unloaded. This improves system performance while not risking low-memory
problems.

The memory allocation routines, on failing an AllocMem() will go through and
flush all EXPUNGABLE resources and then try again. This is what the program
FLUSH does - it simply attempts to allocate an impossibly large memory hunk and
that automatically flushes all flushable resources.
