This is starting to ring a bell, I've seen this with Tk, you need to reuse your threads, because the refcount is so complicated, that Perl won't free the thread's memory when it's undefind. What I do in Tk-with-worker-threads is create 3 reusable worker threads( you would want to create 20). My example looks complex because I use a bunch of hash names, but you can simplify it for your purposes. What I essentially do, is store the available threads in an array @ready. I shift off a thread as I need a thread to work, and when it is done working, I push it back onto the @ready array for next use. This way, only 20 threads ever get created, and only 20 max can run at a time. It works to conserve memory by reusing the threads. You only need to join the threads once, when exiting the program.

So instead of spawing a new one as an old one dies off, push the dying one onto the @ready array, and shift one off for the next thread. Believe me, it works and is solid, and avoids the refcount problem.( To avoid confusion, when you get a worker, a little popup appears that spawns an xterm, just close the xterm to start the thread running. On win32 change the cmd to something that works. I did this to give a visual indication that the thread was actually doing something).
