If you use shared arrays or hashes, Win32 perl will leak handles if you use threads. It will leak 2 handles per thread. If you're only starting say a couple of threads an hour, no problem. If you're starting hindreds, within a week or so, you'll run out of resource space for the process and it will crash.
The leaking handles is a known bug when using threads on Win32.
