Printing start,stop,stop-start inside that method would be an easy way to
find if that is the case.
The following idea could help to fix it - at least, avoiding to read the
whole message at once:
self._message_factory will eventually call the mailbox.Message
constructor, which accepts a file object too (instead of a huge string).
In that same module there is an utility class, _PartialFile ("A read-only
wrapper of part of a file"). _mboxMMDF.get_file() does return a
_PartialFile object, so I'd try this code (untested!):
def get_message(self, key):
"""Return a Message representation or raise a KeyError."""
msg = self._message_factory(self.get_file(key, True))
msg.set_from(msg.get_unixfrom()[5:])
return msg
