You can implement this "by hand" quite tidily, using setjmp, longjmp
and a bit of jiggery-pokery. You need a small function that uses
"setjmp" to calculate the amount of stack used, then save that portion
of stack as the "thread". Then, a small table that identifies each
stack, and "invoke" and "respond" routines that let you pass
arguments and results through. All this takes is a little experimentation
as to the contents of the JMP_BUF struct as your compiler sees it.

Then comes the hard part: getting each thread to stay out of each other
threads globals :-).
