bug#11268: Rgrep can get out of hand, so...

Reminds me that I think we should have a global key binding for "kill
the current buffer's process" (which should also work to kill a process
which is conceptually linked to the current buffer but runs in another
hidden buffer, as in the case of *vc-dir*): the rare times that I need
to kill a process, I need to do it ASAP and I always find myself
scrambling around, trying out madly the few key-bindings that come to my
fingers (among which C-c C-c seems like a natural fit, according to my
fingers, although I usually prefer to associate it to things like
`compile', or `send').
