Unfortunately, the problem is more serious than having to restart
offlineimap. After the sync finally completed, one message was missing
from the local IMAP folder, and 55 messages were duplicated!
When syncing another large folder, I didn't notice any missing or
duplicate messages, but offlineimap did lose all the
read/replied/flagged flags, so I had to delete the imap folder and
redo the conversion.

Given that the problem seems to cause corruption, I think it's worth
looking into further.
