At this point, how many platforms are there that support libqthreads
and guile, but not posix threads?  If there aren't any and presuming
your idea works out, could we just drop qthreads in favor of posix
threads?  What would be the tradeoffs?

(I'd love to get rid of the qthread per-platform special-casing in
 debian/rules.)
