My first reaction was that you don't know what you are talking about. of course the PAD of the function will exists, and be copied to the new thread. the content of the PAD should not be copied.

And then I tested it out: 

#!/usr/bin/perl -w
use strict;
use threads;

sub thr {
    print "Thread running.. Done.\n";
}

sub run_test {
    my $x = bless {}, 'Obj';
    threads->create(\&thr)->join();
}

sub Obj::DESTROY {
    print "Destroyed from thread ", threads->tid, "\n";
}

run_test();

and the output: 
Thread running.. Done.
Destroyed from thread 1
Destroyed from thread 0

So now I think that I don't know what I'm talking about.
Why did Perl copied the $x? it is not a global, and was not passed as parameter. I just don't get it.

If someone can point me to a relevant perldoc, I'll be greatefull.

thank,
