Hi,

I need a binary/script (php) that does the following.

Start n process of X in the background and maintain the number processes.

An example:
- n = 50
- initially 50 processes are started
- a process exits
- 49 are still running
- so 1 should be started again.

Please, this is urgent.

Thanks! Michael
