Thanks for testing the network settings though it was important
to eliminate that possibility. I've also gotten a report off-line
that logging is not the culprit. So far the only commonality
appears to be high CPU usage. My commit slightly lowered CPU usage,
but increasing that timeout further won't do much.

I plan to run an oprofile on mythbackend with a couple HDHomeRun
recordings going sometime in the coming week. Even though I'm not
seeing the issue on my i5, it should still show where CPU is being
used and hopefully show something useful.
