Urgh.  I would really like to avoid 'one byte left on the socket' games.
The GnuTLS library tried to play those games, and we lost out badly when
something subtle broke it.  I would prefer a way to indicate to the
event lib that it should do this timed event at the end of the queue, if
that's what we actually need (otherwise, it all breaks if the event lib
changes it's ordering).
