Hard to say. 'ps' gives some great information about cpu/memory usage
that may be hard/costly to put in shared memory. One idea should be to
issue periodic 'ps/kill' commands though a telnet/ssh pipe to the
remote machine, or just to the remote X display option.

Of course, getrusage() gives us much of that information.
