I'm curious about the why/which in this. I just ran you test code several times and even put it to 1e9 and 1e8 which both ran out of memory before completing and I got no "Repeat" deaths. This is on a modern Linux box with Perl 5.8. What hardware/perl combination makes yours bomb out so early?

I did mention the reason. MS' CRT rand() function uses 15-bits only.

This also affects Perl directly because the perl's rand is implemented in terms of the crt function.

I'd normally use Math::Random::MT for anything where I need a descent random, but the standard implementation (and therefore the Perl module) is not threadsafe due to some static internal buffers.
