Something I noticed in the manual mentioned that you can chain 
interrupts to run before your TSR. Has anyone used this to get a VERY 
small DOS shell? Ie hook int21 with chain before and popdown sleep? That
way when the shell calls int 21/4c to quit it would pull your code back?
You'd obviously need someway to get it to shell after you do that POPUP 
INTERRUPT, but perhaps it would be possible to set some sort of flag in 
your code and an int 1c trap to check every so often to see if it is 
set?
