I don't doubt it.
Buy why use Ctrl-C?
It's like using the "X" button on a gnome WM decoration to maximize the
Window.  It simpley makes no sense.

A couple of possible solutions spring in mind.
A. Enable Ctrl-\ (SIGABRT) kill yum.
B. If you hit Ctrl-C twice, kill yum.
And my favorite:
C. Move mirror switch to a different keyboard combination (Ctrl-M?) and
return Ctrl-C to its default behavior - graceful shutdown.
