[Yum] Why is yum not interruptible with SIGTERM/ctrl-c?

[Juergen Botz]

Maybe this is a stupid question... and to be honest I have not
looked at the code.  But there have been many times that I 
really needed to terminate a running yum, and right now I have
to use SIGKILL and then I usually need do a 'clean metadata'.
At best this seems to be bad UI... users need a way to cleanly
stop any process on the system.
