  Correct me if I'm wrong, and I'm not an expert here, but aren't
fibers effectively cooperative threads? Isn't it likely that a blocking socket
read would block all the fibres? If not, they'd have to be real threads,
which would seem to imply you'd still get the context-switching overhead
that makes lots of threads bad news.
