title: Safe perl threads
body: <p>I'm trying to run a perl script with threads using the detach methode. The application
  is supposed to run permanent, 24/7. I'm trying to use the <a href="http://cpansearch.perl.org/src/JDHEDDEN/threads-1.86/examples/pool.pl" rel="nofollow">this example</a>.</p>
  
  <p>But when i run this example in a longer time period it turns out that there is a constant 
  increase of memory. How can i avoid this? How can i use the <code>threads-&gt;detach</code> method without the increase of memory?</p>
