Thinking about this even more; I don't think it's possible to
preserve round-robin recv_io/accept behavior I want from
blocking on native threads when sharing descriptors between
multiple processes.

So a new class it is...

": a small thread : a delicate filament"

How about we use Threadlet to discourage things we don't like
about normal Threads (such as Mutex, ConditionVariable, ...).

s/Fibers/Threadlets/; but yes, I think it should be possible
to have something like Threadlet.exclusive { ... } to prevent
auto-switch surprises (like Thread.exclusive in 1.8)
