OK, so there's design work to do here. (Or at least, things to think
about.) But that's OK. It's new and exciting. :-)

I have a vague recollection of there being a situation to do with
calling foreign code that makes all Haskell threads block in the
non-threaded RTS, but not in the threaded one. Depending on how big your
send and receive buffers are and how long everything is blocked for, it
might not matter. I just thought I'd ask about it...
