You could use Thread::Suspend to put your thread to bed. With Thread::Suspend, you can suspend and resume a thread. For example, just using one thread: 
#!/usr/bin/perl

use strict;
use warnings;
use threads ('stack_size' => 16384);
use Thread::Suspend;

$|=1;

sub start_thread {
    my @args = @_;
    print('Thread started  ', join(' ', @args,), "\n");
}

my $thr = threads->create(\&start_thread);
$thr->join();

my $tid = threads->self;
$thr->suspend($tid);
sleep 1;
$thr->resume($tid);
