All of my utilities hook 8 and first call the old 8 then they sit
in a semaphored section donig there stuff.

This was because way back a lot of TSRs didn't chain to the old int 1C handler
so all of a sudden you lost touch with timer ticks.  Everyone passes 8 on
or your machine would lose track of time.
