I played a bit with your code, and I just want to register my confusion on a couple of matters. First, on this:
foreach my $thr (threads->list) {
    # Don't join the main thread or ourselves
     if ($thr->tid && !threads::equal($thr, threads->self)) {
         $thr->join;
            }
        }

The main thread has an id of "0", and threads->list doesn't seem to return thread 0, so I wonder if that's a bug in the list() method, or if the conditional before the join is unnecessary.

Second, on this:

    my $GetProcessMemoryInfo = Win32::API->new('psapi','GetProcessMemo
+ryInfo', ['I', 'P', 'I'], 'I') or return $^E;

I thought it was a waste linking to that function on every call to it, so I tried to move it (and the other Win32::API function definition), to near the top of the program, but it ended up crashing perl. If I defined it near the top, and still defined it again on every call, it worked a couple of times, but then returned "The specified module could not be found" trying to link to it again after joining the threads.
