Im looking at adding threading to php, (for the cgi/cli stuff).. The story so far: I've created an extension which diverts all zend_execute calls into the extension -> phpthreads_execute. this function is a copy of zend_execute with a few modifications - to copy & restore things like EG(active_symbol_table); - to malloc lock and unlock the execute loop and release on each opcode.

Ouch. While it's an interesting way to deal with the issue, I think this will be way too slow, and maintenance will be hard (keeping up with changes in the real zend_execute, and zend engine in general). As in a couple other responses, the way this needs to be implemented has been hashed out, largely based on how the same problem is solved in Perl (there is a remarkable amount of simularity between PHP and Perl at some levels). If you're interested, lets talk. Shane
