Hmm.. I'll have to look at this some time. I'm not entirely happy with 
the design of the CPUWatcher, as it keeps making new processes that 
tend not to get garbage collected for a while and so clutter up the

You can (as I recall) make a Process subclass that adds a name 
instance variable, and start up named processes.

At one time I had support for process names in the ProcessBrowser but 
it doesn't seem to be there any more.

Or you could just have your processes added to a global WeakSet when 
you make them.

Then you could run through the WeakSet after doing a garbageCollect 
and terminate the appropriate processes.
