There's been a lot of hard work put into the threads subsystem, and you also should make sure you're using the latest versions of threads.pm.

Unfortunately, the later versions of threads seem less reliable than that which shipped with 5.8.6.

Specifically, leaked scalars seem to abound during global destruction, and traps when joining or detaching threads are more prevalent. This seems to be true of the CPAN version in conjunction with 5.8.6, 5.8.8 and 5.10.

I don't have a clean example to demonstrate this yet. but threading definitely seems less stable since the version that shipped with 5.8.6 was superceded.
