wrtr:
   DEBUG[imap]:   33:06.96 wrtr > CNEO10 FETCH 1:41740 (FLAGS UID 
INTERNALDATE)\r\n

which in turn causes:
redr:
   DEBUG[imap]:   33:07.08 redr < * 1 FETCH (UID 1 INTERNALDATE "06-Dec-2005 
21:13:19 +0000" FLAGS ())\r\n

When I get 41740 UIDs back with a long internaldate that I'm not sure I need, 
it doubles
the size of the replies, subsequent traffic, and causes me to download over 1GB 
a day 
for only syncing my folders every 15mn.

offlineimap should only need the UID for syncing purposes, should it not?
