I sincerely appreciate your offer, but I don't think it will help.
I've tried to replicate what these are processes are doing as a
standalone program and haven't been able to replicate the problem.
Maybe there's something about the order or timing of the operations
that I'm not capturing.
I'll take another look at my test program and see if I can get it to
trigger the problem.
