You are right.  Intermediate MTAs and queueing effects may cause
arbitrary reordering of the messages.  Some of the intermediate messages
may never be delivered too, but that's another story.

How about inserting an RFC-compatible "Date:" header with an incremental
second count?  This /may/ help with mailers who resort, unless they look
at the 'envelope date', in which case we are screwed without a sleep
between every single patch message.
