100 messages limit, on multiple IMAP->Maildir accounts

[Daniel Shahaf]

I'm syncing a new laptop and offlineimap hangs after downloading about
100 messages.  (See transcript below.)  Upon restart, it proceeds to
download another 100 messages or so and hangs again.

Possibly related: today I observed several times an issue whereby
offlineimap marked a folder as "done" in 5 seconds or so, even after I
flagged a message on the IMAP side (to force a non-inoperative sync).
I've observed a similar limit (100 messages) today also towards the end
of syncing a largish folder (11000 messages, totalling 99MB).  I have
also noticed a similar 100 messages limit on my desktop offlineimap
installation against my ISP account.

How can I cause offlineimap not to freeze after downloading 100 emails?
Several of my mail folders are liable to get >100 messages in one sync
on a regular basis.

Thanks,

Daniel
