use threads ('exit' => 'threads_only');
use Thread::Queue;

#create child threads
my $childs = 2;
my $Q = new Thread::Queue;
my @kids = map threads->create(\&processData, $Q), 1 .. $childs

# this is how queue work for the processData() once I get some work to do
$Q->enqueue($work);
sleep 1 while $Q_->pending > $childs;

### How I can check for any errors in a thread here? 

#Join all the child threads once every work is done
$_->join for @kids;
