Yeah.  What this means is that select() examines the slots in the
vector numbered 0, 1, ..., nfds-1.  If you pass `1' as nfds, then
select() will only look at the settings for fd 0.  This is a goofy
interface.  Maybe we ought to use poll() instead.  I don't know.  I
use select() since I have a bsd-ish background.
