Marking proxy servers as zombie - odd behaviour

  Yes.  Many packets lost.  The NAS re-transmits, FR re-transmits, and
the home server doesn't respond.

  The default timeout before marking a home server zombie is 30s.  If
there aren't *any* responses to retransmits in 30s, something is very wrong.

  I'll take a look at making the zombie code less aggressive.
