Now I remember...
I left out a relevent fact: I'm not the one calling IMAP4_<whatever>.
That's being done by the imapclient library. There's no way to pass
imapclient a custom class to use. It's hard-waired to call either
imaplib.IMAP4_stream(), imaplib.IMAP4(), or imaplib.IMAP4_SSL(). I
could create an IMAP4_TLS1 class, but I would then have to sub-class
imapclient.IMAPClient and override its _create_IMAP4() method to make
it call my IMAP4_TLS1() class instead of calling imaplib.IMAP4_SSL().
Monkey-patching imaplib seems a little better since it it doesn't
depend on assumptions about the internal workings of imapclient (other
than the fact that it uses imaplib.IMAP4_SSL).
