The code is:

  response = imapobj.fetch('1:%d' % maxmsgid, '(FLAGS UID INTERNALDATE)')[1]

meaning that it obtains (FLAGS UID INTERNALDATE) for all messages in
a folder every time.

It needs to do this to be able to synchronise flags. But does it
mean that the server has to keep it all in memory? I am not sure...
