Bug#700624: creating and destroying threads with perl results in memory leak

[Stefan Priebe]

Package: perl
Version: 5.10.1-17squeeze4
Severity: important


creating and destroying threads in perl results in a memory leak.

Mini Testscript which works fine under Ubuntu 12.04 perl 5.14:

use threads;

sub ThreadRoutine {}

while (1) {
    $thread = threads->new(\&ThreadRoutine);
    $thread->join;
}

This results in heavy memory leaks on Debian Squeeze.
