Unfortunately PHP was never and will most likely never be threadsafe as
a module.
(Yes, I know that there's the ZTS code, but hey, are you really serious
about this?)
I never understood why the core devs never switched to a threaded model,
but I believe they never deemed it truly necessary.
The ZTS threaded module has a few interesting approaches but fails in
some other areas. To be honest, I suggest to use the fpm-cgi SAPI module
with an Apache threaded environment.

Sorry, didn't read it.

Yes, it is. Doesn't change the fact that PHP is not threadsafe.

No, there isn't. But if you run php via fpm, it doesn't really matter
anyway.

I use an event MPM on my server with an fpm cgi module
