Hi Monks,

I'm trying to run two functions in parallel thusly: 

#!/usr/bin/perl
use 5.014;
my @child_pids;

for my $cmd (\&test1, \&test2) 
{
    defined(my $child_pid = fork()) or die "Couldn't fork: $!";
    if ($child_pid == 0) 
    {
       exec $cmd->();
    }   
    else 
    {
       push @child_pids, $child_pid;
    }
}

for my $pid (@child_pids) {
   waitpid($pid, 0);
}

sub test1
{
sleep 3;
say "in test1";
}

sub test2
{
sleep 2;  
say "in test2";
}

Output: 
in test2
in test1
in test2

[download]
Say what? Why is it running test2 twice?
thanks for any responses
