Personally, I'd re-cast your main loop as: 

while( 1 ) {
    my $c = $lsn->accept;
    print "Client connected: $c";
    threads->create( \&do_stuff, $c )->detach;
    undef $c;
}

Whether that will make the slightest difference on your platform/versions I cannot test, but I have a hunch it might.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
