Ok, so it's just not just me, good to know.

With offlineimap 6.4.1:

I just ran in debug mode today, and there is however a bug in offlineimap
where it does not restart on its own when it should:

Note that it actually hangs for a long time between the first socket error
where it should have ended on its own, and the 2nd one where it didn't
stop/restart either, but just hung.

It just hangs there and needs to be manually kill and restarted.

Surely, this could be fixed/improved in offlineimap, right?
