I haven't had the time yet, but if time.sleep() really pauses without internal active waiting that is definitely an improvement and the 30 seconds delay is totally acceptable.

If I have a moment tomorrow I'll try that. Another thing I was considering as a work around was to completely remove keepalive timeout functionality and place a cron job to restart offlineimap every 30 minutes, but I don't know if that would be better for battery life or not, since startup has its own peak of disk access and CPU use.
