If you just want working code, I have the perfect solution for you: Parallel::ForkManager. Perfect fit, so to speak

if you want to know more about fork and wait, just use "perldoc -f fork", "perldoc -f wait", "perldoc -f waitpid" and "perldoc perlipc". Or read the corresponding man pages of the underlying C library.

Basically you should be able to do up to 4 forks, then just wait until you wait()ed an equal number of times (or better until wait() returns -1). Getting the first 4 entries of an array is easy, just use my @part= splice(@array,0,4). How much you really get out of the array (because it may have only 1, 2 or 3 entries left) you will find out with scalar(@part)
