Subject: [Response] Storing array of background PIDs

I remember that in the first assignment, I made a global array of inode numbers that gave me trouble when I forgot to clear it of its contents for the next call to our function from Prof. Eisenstat's main() function. 

Based off of that experience and how similar this situation is, I'd say that maybe a global would store your backgrounded PID's between calls to process(). Good luck.
