Ok.. So, a lot more digging.

This issue appears to be fixed in offlineimap trunk, and is largely a dupe
of http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=569068.
, and in released version 6.3.3. Additionally, debian has 6.3.3-3, so I
will get that pulled into Ubuntu. I obviously should have checked there
first, and have requested sync from debian under bug 793574.

Previously, I had arrived at https://github.com/jgoerzen/offlineimap/wiki
(its the top hit on google), and then at
https://github.com/jgoerzen/offlineimap and, as a result was looking at
the wrong trunk. Apparently, I can't read a file named 'README'. Sorry
for that.

The only thing I would suggest is to remove or update the obsolete comment
in offlineimap/imaputil.py:WrappedIMAP4_SSL, that says:

    It provides a better readline() implementation as impaplib's
    readline() is extremly inefficient. It can also connect to IPv6
    addresses."""

This class no longer has a 'readline', and python's socket performance
issues may have been fixed under current releases of 2.5, 2.6, 2.7, and
3.X (http://bugs.python.org/issue2632).

Again, sorry for the spam, and thanks for offlineimap.
