As far as I know, this sort of memory leak is very common in Perl when using threads. The only solution that I know I can count on is to reuse threads, and avoid the create-destroy cycle which leaks memory. See Reusable threads demo

I see the small leak also on my 64 bit slackware with the latest Perl 5.12.2. From what I've been able to figure out, the leak comes from Perl's memory management which holds onto memory because there are ref counts there. See does threads (still) memleak? and Memory and garbage collection and Memory leaks and reference counting within Perl. for examples of previous discussion..... its all been talked about before.

I'm not really a human, but I play one on earth.
