You could put a debug statement into tvwish's backend_command function
in mythlib.pl and see what sort of commands it is doing, and to see if
it doesn't do a DONE.  Seems like a bug in Myth in any event, a closed
socket should be a closed session even if I don't do the DONE, but as far
as I can tell I do.   I don't wait for an answer on DONE but I was just
copying some other code there.
