The CTRL-C misbehaviour is caused by the rpm API taking control of the 
handlers for termination signals such as SIGINT. I've fixed the problem 
in the latest Yum versions (CVS). Yum now only has the rpmdb open when 
strictly necessary so that it can handle signals properly itself.

In the new version, CTRL-C once during downloads causes a mirror switch; 
twice in quick succession causes termination. A single CTRL-C at other 
times should just quit as normal.
