Hmm... TSR... Terminate and Stay Resident... Sounds pretty permanent to me...
Doesn't say, "Terminate and stick around until I decide to free you..." :-)

You can't free memory which has stayed resident as a result of a TSR. 
It's not even accounted for in the system as "allocated" memory -- it's
been UNHOOKED from the memory management lists.  It's GONE.
