I'd say, every time program A or program B runs, save its PID in a file
somewhere (or database table, or whatever). Then, when you decide to
shut down, go through the list in that file and kill all the pids in it.

If you do this be sure to remove the PID entry when an instance of the
program exits or you could cause yourself unnecessary work.
