in reply to wait before forking more

I am curious and want to know if there is a way in perl to wait for a number of processes to finish inside the for loop before forking more

That is exactly what Parallel::ForkManager does! When the forking limit is reached it waits for some child to exit before forking a new one again.

    Parallel:ForkManager does not seem to do this or I am using it incorrectly, this is essentially the structure I am using. 
    foreach $device (keys %devices) {

$pm->start and next;
.....
$pm->finish;
}

    I dont use $pm-<wait_all_children since i want it to continuously get input while children are processing.
