The problem is with the GO32 implementation of interrupts under DPMI.
The first pass implementation I added was a really crappy job.
Under V2 and CWSDPMI interrupts will be as fast (or faster) than with
V1.1x.
Direct screen access will run at the same speed, since it is a memory
to memory transfer. It is the other function that are called which
do int 0x10 calls that are much slower.
