Hi, I'm wondering if there's a reason why PCNTL isn't available on the
FPM SAPI. Is it intentional? Can it be safely enabled?

Should there be a reason for the manual forking FPM children,
changing priorities, or handling signals?
I can't figure out any.

I would not want to predict how the forked process will behave with
the fcgi-connection he got open from the parent.
PCNTL is for the command-line, I belive.

Because there is master process in FPM who manage the process.
2 or more master process will be ridiculous. That's why in FPM disable the
fork.

PCNTL isn't available?
Disable the fork?

What are you guys talking about?
PCNTL is just an extension, you can enable it just as any other extension
when you compile your PHP binary, whatever the SAPI is.

Spawn-fcgi uses a master process, and works perfectly fine with forking.
The only other SAPI I believe that disables PCNTL is mod_php which is
because php lives as a thread inside the Apache process. This isn't
really the same case.

The extension gets disabled depending on the SAPI. The mod_php SAPI, for
example, doesn't detect it at all.

It's different, Cause FPM will conflict with fork action.
In any SAPI other than CLI, fork will be troubles.
In the new process,It destroy the normal processing life-cycle .

just a few words on why you don't want to shoot in the foot
