Have a second subscription to "Recording finished" which kills each bump script. You could have the bumper write its pid to /tmp/myth.%FILE% so the recording finished script knows who to kill.

Hmm, system events might work.  At first glance, however, it looks
like there could a tiny race condition.  The client might not receive
the REC_FINISHED even in time to stop the periodic handler before the
recorder has already started another recording.

This does give me a different idea, though.  The channel change script
could kill any existing handler, change the channel and then start a
new handler.  I'll have to give that some thought.
