That's the commercial flagging thread. It runs with a nice priority of
19, so even though it looks like it's eating up all your CPU resources,
the kernel process scheduler will easily preempt it if something else
needs to run. Search the archives for "commercial flagging thread" for
more info. It usually takes about 1.5x the length of the recording
it's flagging to run. You can disable automatic commercial flagging in
the frontend setup, if you like.
