Combined FE/BE.  Commflags run low priority, and mythbackend doesn't take 
much cpu, but the frontend has become a disaster.  Right now I'm watching a 
hidef stream ('Cops' off fox) and its chunky, with hesitations/skips every 
5-15 seconds. Nothing else going on (no recording, no jobs).

In .18 I could commflag hidef in realtime, so it only ever had one job at a 
time.. now its 2-3x realtime (and it gets worse since it ends up flagging 2 
shows at a time.)

Its not IO bound (or doesn't seem to be):
Cpu(s): 52.5% us, 41.9% sy,  0.0% ni,  5.6% id,  0.0% wa,  0.0% hi,  0.0% si
