I'd expect that the output of M-x list-processes RET helps me for a
subsequent M-x signal-process RET. Alas, this is not the case:
list-processes doesn't print the process id and signal-process
doesn't know about process names.
A simple workaround would be to have list-processes show the pid.

Allowing the user to enter the name of a process in addition to
a numeric pid to signal-process would be trivial enhancement to
signal-process:

A more complex approach would be to make the list-processes buffer
obey a mouse-3 click on a process to pop-up menu which allowed you to
terminate them using the mouse. [and suitable keyboard short-cuts as
well of course].

Please disregard the patch I just sent; it breaks existing use of
signal-process!
I'll make a proper patch if there is any interest in adding this.

Well, I'd be interested, and Richard at least isn't opposed, so if
it won't cause you too much trouble...

It seems like a useful change--please install it.
Would someone like to add a suitable command to the list-processes buffer?
