I can reproduce this with Debian squeeze, and agree that it's a bug.
I am tentatively going to suggest that this is the same bug discussed
(briefly) in [perl #69598]. In my reading around the subject of memory
leaks in threads, I was unable to conclude anything definite about this
bug, so I doubt that we will be possible to fix it in Debian squeeze
unless something more specific comes to light.

Thanks,
Dominic.
