It does indeed contradict me. It looks like this is
implementation-dependent, because I distinctly remember
encountering a bug once that I traced back to the fact
that I wasn't servicing *all* the fds reported as ready
before making another select call.

Since then I've always been careful to do that, so it's
possible that the behaviour has changed in the meantime
and I haven't noticed.
