Rebuilt the software on the slave backend with debuging, and tried to
reproduce the failure again (twice), but now it is working fine.  It
is interesting that it failed for me in the same way two times in a
row.  Guess that was just luck.

I will bang on it some more tomorrow night.

As far as the mythsocket stuff goes, so far I *really* like it.  It
has been a long time since my backends and frontend have re-synced
this well.  For about the last year, if the backend was restarted, the
fronted would hang for a LONG time.  With the mythsocket patch it
resyncs nice and quick.

I have nothing of any importance scheduled to record in the near
future, so I will continue to run with this patch.  I will let you
know if I find any (other) problems.  I will try to reproduce the
record failure and get you a BT.
