Thank you for posting this.

I have a question about the failed ithreads experiment though. I thought the biggest problems with ithreads were that:

• They don't use native threads; the entire program is still a single process. (I don't understand the Windows threading model, but I'm pretty sure what I said is true on Unix-like platforms.)
• There's still way too much global state in Perl 5.
• Cloning an interpreter and the global state is hideously expensive.

Those all seem like implementation details, where the most important point of an ithreads model is default shared nothing -- which has tremendous advantages with regard to locking semantics.

What am I missing?

Update: audreyt and Liz are right; I read the threads source code, rather than grepping through the *.c files for Pthreads calls.
