CGI?
If I'm having a PHP extension forked along with an apache child process,
that extension has initially not had a database connection, but it's established
when processing requests,,, that connection can get forked along with a child
process?
(In other words and repeating myself a bit: apache forks it's child processes
after they have already been processing requests?)

Note that I'm considering prefork MPM and PHP scripts.
