This whole question put another way:
Obviously, if you start something with "run", you want to end it with
"kill".
Obviously, if you start something with "attach", you want to end it
with "detach".
[These are not hard and fast, of course. You can detach a run process
or kill an attached process. But you surely see what I mean - they're
logical opposites.]
If you start something with "target", how do you end it? I propose
"disconnect".
