Well, the problem is that the mouse driver can unload ITSELF.  And TSR's need
to maintain about 16 bytes of memory (well, the PSP is 256 bytes, in cases
272 bytes, plus the memblock headers, so a grand total of 304 bytes) so that
another TSR chains to the same interrupt that was loaded after them.  If a
program didn't chain to its interrupt, it could totally unload.  The way to
do it is to know what interrupts a TSR changed, and to see if those
interrupts still point to that TSR's memory.  If not, the TSR CANNOT be
unloaded unless it can unload itself.
