Beware, BizTalk creates zombies!

I have been working a couple of days with a resequencer orchestration. For those of you that doesn't know what I'm talking about; the resequencer pattern deals with putting a sequence in correct order. That is if i send the messages 2, 1, 3 the resequencer patterns job is to send them in the correct order, that is 1, 2, 3.
