A lot has been said in this thread already. And in Things you need to know before programming Perl ithreads I describe the current status of threads in Perl as I see it.

I agree with chromatic's comments. Perl threads currently provide an interface to doing threads in Perl over doing non-portable stuff in shared memory. It makes it easy and portable. It's not really production ready, especially for a mod_perl environment.

I also agree with most of Abigail-II's comments. Fork() is very cheap on modern *nix systems.

Which is why my forks.pm module gives you a bit of the best of both worlds: the memory savings of fork() and the ability to use a standard Perl executable (even with 5.6.x!) and the portable interface of threads.pm and its shared variables. At the expense of CPU and latency: there is always a price to pay!
