If we find thread safety problems in PHP we will fix them, of course. It's not like we ignore them. Same goes for extensions, except for those which are specifically designed to access libraries that show no signs of ever becoming thread safe.
At the same time, you need to recognize that developers work on what interests them and what they personally have a need for. I can't speak for everyone, but a good number of the core developers lean towards the robustness of a multi-process architecture. Having separate memory spaces makes everything easier to debug and when something does go wrong it doesn't take down the whole server. These are both very compelling reasons to stick with this architecture. -Rasmus Ron Korving wrote: > Nonetheless, Rasmus, isn't it something to work on?
