to bind the extender, you need to pay extra for dos4g/pro

well, if you used pmode/w which is another dos extender for watcom, the
interrupt latency is extremely low - it was originally designed for things
needing fast response like games and demos.

the only real mode code that ka9q would need to call is the disk read/write
code, and i'm sure a fairly effective block cache/serializer-type thing
could be implemented to minimize the overhead of that cause of switching
modes.

i think it's a reasonable idea.  but i'm not willing to code it, cause i'm
happy doing my net access with a combination of win95, nt and linux.  :)
