The statement about non-shared APCu data between FastCGI workers is confusing

[andrew-demb]

I think the statement

Note that when running PHP as a (Fast-)CGI application inside your webserver, every PHP process will have its own cache, i.e. APCu data is not shared between your worker processes

is confusing - because the most popular (Fast-)CGI implementation - php-fpm shares cache between worker processes (as of https://github.com/krakjoe/apcu/issues/121).

There is a difference between using fpm and using fcgi, I should probably put in a PR to phptherightway to clear it up.
