Hi, I know that a Ruby process with PID 1000 (under Linux) has forked 4 times. 
How could I know the PID of those childs from any other ruby interpreter?
This is, I just know the PID of the parent (1000).

Of course I could do some hack as inspecting the output of "ps" and inspecting 
the pid/ppid, but I'd prfer a ppure Ruby method for this.

Thanks for any suggestion.
