I don't think you're experiencing a leak per se.

On my iBook starting 100 threads without loading any additional Perl modules apart from "use threads" costs more than 31 Mbyte of memory. You might want to check this for yourself with my Benchmark::Thread::Size module like this: 

$ perl -MBenchmark::Thread::Size=refonly
  #   (ref)

Your sample code seems to want to start 1000 threads. Be prepared to have at least 315 Mbyte of memory available for that. Unfortunately, in my experience, any serious program very quickly takes at least 1 Mbyte per thread. So you better have a lot of RAM available if you want to start 1000 threads that way.
