  Does reverting to pre-July 20 get rid of your problem?  Note that the
  originator of the first Email mentionned that he is running what
  appeared to be stock 5.1-RELEASE, which may or may not be related to
  what you're seeing.

  If reverting to pre-July 20 gets rid of your problem, perhaps we can
  figure out what commit triggered this behavior for you.  Also, do you
  have PAE enabled?
