You could try linking Ruby with GNU pth (or GNU nPth).  I think pth
comes with pthreads stubs, so maybe you can get that working (and
report back your experiences :)

I suspect pth will conflict with Fibers, however.

I know you don't like fibers, but the "neverblock" gem uses Fibers
transparently under 1.9 to provide green threads.  However, I'm
not sure how active "neverblock" development is these days.
