Without complete resource tracking, a task can't just be indiscriminantly 
killed.  However, since all tasks are likely to know how to shut themselves
down, there's already a command that works very much like the KILL command
you propose.  It's the Break command.  You'd type something like:

	1> Break task 3 e

What this will do is set the ^E signal in task 3 (you could also specify the
^C, ^D, or ^F signals).  A properly written program will see this via either
a polling or an exception, and shut itself down.  Try this with the Dir
command, which responds to ^C.  Start up a background Dir (in it's own window
to make things easier on yourself), like:

	1> run Dir >con:10/10/200/100/DirWindow opt a
	[CLI 2]

And you see Dir chugging away in it's window.  If you then type:

	1> break task 2 c

you'll shut down the Dir window as Dir responds to the ^C signal.  And that's
really all there is to it.  Not as powerful as a UN*X "kill -9", since the
task being killed must cooperate, but useful nonetheless.
