I still haven't found what is hurting us so much. But there is one thing
that I noticed when profiling. On a very slow WLAN, from 4 seconds
total, I was spending 1 second in imaputil.py:flagsplit() where *a lot* of
time was spent in the various debug() commands in that file (notably in the
options2hash function).

I did NOT have debug enabled, so they did not do anything, but cost me
0.5sec out of 4 seconds (again on a slow WLAN).

Try to remove all calls to debug() in imaputil.py and time your
syncs before and after, I would be interested to see if you see
improvements.

If that is the case, we would have one more reason to more to a real
logging system. (my favorite would be python's logging module).
