I can't reproduce the problem with 3.3-STABLE, and if a problem in 3.3-RELEASE doesn't exist in 3.3-STABLE, there's nothing we can do about it now. Also, note that the problem is not that more "eats up CPU" -- I'm pretty sure it's just spinning on input, so if the system got busier, you'd probably find that the CPU usage of the more processes would flatten out. The problem is simply that the children of the shell process should die when you kill the shell. Ciao, Sheldon.
