How can I get the PID of a program run in a ruby script. I've 
looked at open, popen, system, and %x//, and various Process 
methods, but haven't figured it out.

The program runs in a loop, calling a method to for command line
parameters. I need a way to send a SIGTERM to the program so it
will be run again.

"Programming Ruby" references are welcome. Thanks.
