Comment(by eharris at puremagic.com):

 In case it is helpful, I've narrowed down what seems to be the cause of
 the problem.  Whenever the backend actually deletes a recording due to the
 backend getting below the minimum free space limit, shortly thereafter the
 system goes into the highly loaded continuous issuance of SCHEDULE_CHANGE
 messages.  Just to be clear, this is NOT caused when a program is marked
 as deleted, only after the video file is actually deleted.  One additional
 nuance is that while the load increases significantly (until being "fixed"
 by restarting the backend) with a single recording being deleted, it
 usually takes two deletions (on my system) before the load goes high
 enough to be user-visible and cause problems (video skips, delayed
 responsiveness, etc).  Three or more deletions usually makes the system
 practically unresponsive, so the load generating effect seems to be
 cumulative.

 I can't tell for sure from trac or the changelog, but has this fix made it
 into the 0.21-fixes branch?  If so, I will upgrade my system to a later
 version that includes the fix to see if it resolves the issue I am seeing.
