And looking at imaplib2 source:

IMAP4.open() connects to the server, then sets self.read_fd
and starts the self._reader thread, which uses select()
and read() on the socket.

Then starttls() calls ssl.wrap_socket() and updates self.read_fd,
but it seems the self._reader thread eats part of the SSL handshake.

I think to fix this starttls() needs to be done before
starting the self._reader thread.  (Or the thread needs to be killed
before ssl.wrap_socket() and restarted afterwards.)
