[mythtv-users] slow mythbackend scheduling

[Mark Covington]

My setup was running fine ~2 weeks ago, been keeping up with 
myth-commits, but haven't seen anything that would cause this problem.

Here's my symptoms:
*Recordings start ~10 min late but stop correctly
*Backend uses 100% CPU for 3-4 min during startup and during any 
schedule changes.  I watched the -v all output and schedule changes 
would take 3-4 min with the backend spiking the CPU.  During this time 
mythweb/mythfrontend would time out and say the backend was not running.
*mythbackend doesn't crash, just spins 100% at points
*Scheduling changes used to be immediate
*thought it might be database corruption, but mysqlcheck gave all OK's

Any suggestions?
