I spent the better part of 3 or 4 days trying to track down the horrendously
high CPU load of mythbackend. I tried the MySQL tuning. I checked, fixed,
analyzed and optimized MySQL. I stopped and started all of the
myth processes. Then I did the trick above. FIXED.

Hope anyone else searching around finds this post sooner then I did.
