Hello there, I'm doing my first tests with threads in perl. Using the worker-model my program starts several threads and detach them. Unfortunatly after the threads ended up, it seems that perl doesn't clean up the memory. The program uses as much memory as before. I tried a little test program: 
use threads;

my $i=1;
while($i<=50){
    my $thr = threads->new(\&lwp);
    $thr->detach();
    print $i++, "\n";
    sleep(1);
};
sleep();

sub lwp {
    sleep(60);
    print threads->tid." ended\n";
    return 1;
}

After starting the 50 threads the program consumes approx 18 mb of memory, after the threads ended this is slightly reduced to 17 (running perl 5.8.4 on a linux machine). Anyone can help me with that?
