[pkg-lighttpd] Bug#457290: invoke-rc.d lighttpd stop does not stop php-cgi

[Stefan Bühler]

Hi,

> "socket" => "/tmp/php-cgi.socket" + var.PID

this is a really stupid idea: that way you just keep spawning new backends 
with every lighttpd restart, and the old backends will still be running too.

Recommended way is to use runit or daemontools/supervise with spawn-fcgi, that 
way you can restart php without lighttpd (and the other way round), and have 
php run with a different user (always a good thing for security).

I'd love to have some useful debug info on this, so if you can reproduce it 
and get a strace of it (lighttpd *and* php), that would be very nice.

The last strace someone had showed that lighttpd did the correct kill(...) 
call (there was no strace of the corresponding php backend).
