Good questions indeed.  I spent a bunch of time investigating this, and
found some bugs that might have caused this problem, although I'm not
certain.

Bruce: Can you please see if the patch below fixes this problem?

Mike: Would you be willing to review this (very small) patch to see if
it makes sense to you?  I'd like a second opinion from someone familiar
with that subsystem before I commit it.

     Thanks,
       Mark
