Yeah, some googling turns up the suggestion that a self-pipe is a portable
way to get consistent semantics from select(); latch.c has already done
that. I suppose that using latch.c would be convenient in that we'd have
to write little new code, but it's a tad annoying to add the overhead of a
self-pipe on platforms where we don't need it (which seems to be most).
