Well, in fact php is also thread-safe (I hope). However, the external 
libraries used by PHP are not necessarily thread-safe (exemple: gd ? 
imagick ? pcre ? dom ?...).

That's why I thought the same argument could be used for mod_python and 
mod_perl if they call thread-unsafe libraries. Now with that Global Lock I 
don't really know :-)
