Most people?  You're in the wrong group.  Try an IBM-PC-specific group.
This is related to neither Pascal nor C.  In comparison to the vast
variety of machines on which one can use Pascal or C, the variety of
machines where your lead-in is true is very tiny - bascially, the
IBM-PC clone world.  (Large in number of machines, small in number of
machine *types*.)

I think you really don't need the speed you think you do.  If you're
really really sure you do, try building your own handler for interrupt
9...just be *very* sure to reset it when you're done!
