Hang on a second, X? Now I see, it even says
X11 in the subject. X11 is the protocol for X.
Do they have signals of their own?!

My answer has nothing to do with X or X11, it
is plain Unix IPC, just two processes
signalling each other...

one doesn't need more keys. It is doing
something sensible with the ones you got that's
