I'd rather like to see a method to tell the kernel to stop a process
instead of coredumping.

That way, the shell will notice, and you can either attach to the thing
with gdb, or tell it to continue (at which point it'll drop core for real).

Appropriate modifications to the shell (or to your favorite window manager)
are then not a problem.

My idea of a kernel interface would be to add another flag bit to the
clone() syscall.
