I've gone ahead and applied that change in Perforce, and look forward to 
hearing back on the testing.

If you can think of other process-inspection related things it could be doing, 
let me know.  The one thing I currently have in mind that I haven't made

signals have handlers, etc), which may be useful when debugging signal 
problems for an application.
