Cannot interrupt offlineimap 6.3.4 from keyboard

[Tony E. Bennett]

I'm in the process of upgrading from v6.0.3.   The new version
ignores ^C.  In fact, it can only be killed with 'kill -9 PID'.

Platform is OSX.  I've tried both python 2.6.1 and python 2.6.6.
Have also tried with and without explicit 'socktimeout = 60'.
No difference.

Is this a known issue?   Something to do w/ 'ui' perhaps?

thanks
