I've a code...i want it to fork (i'm just trying threads/semaphore) 2 threads at a time...
The code i have, spawns 2 threads only first time...i want it to happen in a loop...
Your wisdom is appreciated!
#!
use strict;
use warnings;
use threads qw(yield);
use Thread::Semaphore;

my @array = qw(a b c d e f g h);
my @children;
my @results;

my $semaphore = Thread::Semaphore->new(2);
for my $i (1..5)
{
    for my $j(1..2)
    {
        threads->create(sub{\&sub_fork(threads->tid(),@array)});
    }
    sleep(1);
    threads->yield();
}
sub sub_fork
{
    my ($tid,@temp) = (shift,@_);
    $semaphore->down(1);
    my $pid = fork();
    if ($pid) {
               push (@children, $pid);
        print "$tid -- Running another child process - $pid.\n";
        }
    else {
        print "@array\n";
    }

    $semaphore->up(1);
#    sleep (2);
}
