Yes. I experimented with using spoon for JRuby support in Grit some
time ago. Unfortunately, a large number of posix_spawn() features
require real OS file descriptors and there was no standard/supported
way of retrieving them for most standard Java stream types.

That issue aside, I'm not opposed to using FFI so long as the
performance profile is on par with the C extension. We certainly plan
on supporting JRuby in some way down the road. I doubt the
Process::spawn interface can be fully implemented without real fds,
but we'd like the higher level POSIX::Spawn::Child class to be JRuby
compatible.
