Though I can't actually say *how* we'd do it, another conceptual
arrangement might be to allow an interpreter per-posix-thread. It's
certainly not as transparent as full concurrency, and unless there
were some reasonable way to have all the interpreters share a heap/GC
without heading right back into the problems related to
full-concurrency, then people would have to structure their solutions
to explicitly pass data between interpreters.
Again, though, I haven't thought about this enough to have any real
idea if this is even remotely feasible.
