In a real-time multi-threaded system it is sometimes desirable to 
to switch stacks from within an isr so that the
the "iret" instruction will return to a higher priority
thread. This is a simple matter under DOS, but DPMI seems
to pose various obstacles. Is there a clean solution?
 
Sincerely,

Michael McDonnell
