The _MaxMem trap compacts the heap and purges all purgable blocks.  Most
resources (including fonts) are (or should be) purgable.  The next time
one of these resources is needed (to draw text, for instance) it will
have to be read in from disk.  It's very likely that the disk access you
mention is in response to some _GetResource trap.
