These all have drawbacks. Greenlets are based on non-portable
(and, I believe, slightly dangerous) C hackery, and I'm given
to understand that Lua coroutines can't be suspended from
within a C function.

My proposal has limitations, but it has the advantage of
being based on fully portable and well-understood techniques.
