I have a perl program that runs an external process. The process is a circuit simulator. What I want to do is have multiple jobs put into a queue, and when the process completes, it runs the next file in the queue. This is step- by-step what I want to do: 

1. Submit a system() call if that process is not running.
2. if process is already running, put system call in queue.
3. when 1st system call completes, grab next in queue, and run.

Thanks for the help!
