PCs do have one thing that unix doesn't.  There's a BIOS hook that you
can hook (probably a DOS hook also) that will get called with one
value when the system becomes idle waiting for I/O, and later gets
called with another value when the data is ready.  Basically, on the
first call you start doing stuff, and the second sets a flag that the
first notices and thus returns to the original task.

Not likely to be easy to use under DJGPP, but there it is.
