  Sorry for being unclear -- mid is simply a Message-Id (my e-mail
  client supports directly referencing messages this way; in any case,
  it's a part of message headers so you can uniquely identify a
  message this way). In this case, I meant my message sent on
  2007-09-03 12:37 where I pasted the debug session and my suspicions
  about the infinite loop.

  Recreating the problem would be great, I hope you will be more
  successful than I am -- no idea so far. Should be easier for you
  since you probably have more users with real-life e-mail usage
  scenarios. Let us know if you get any progress here.

  As for debugging, Brian (see previous e-mail in thread) mentioned
  attaching to a process is similar with dbx. I've never used dbx but
  a quick search in Google suggests it is pretty easy to use and
  similar to gdb. Your mileage may vary, though :)
