Cool!
Mingo, another x86 speed related hack you might want to look into is the
new instructions supported by the PII-333 and faster processors. I think
they introduced new instructions for very fast context switching? Saves
all regs in a buffer in very few clocks I believe.
Have we already made use of this feature or not?

PS.
how much trouble and how much faster are CALL GATES?
