If you want to pitch in > support for APC you should just download it (or PEAR INSTALL it from the > command line to try it :) ) I don't think Rasmus was talking about APC. AFAIK he mentioned some extension code that used the Apache SAPI to run a PHP script to acheive what we're talking about (persistent global vars/functions/objects etc).

Rasmus, can you say more about what this is and it's current state of functionality (or lack thereof)?

I don't know what is possible or how PHP internally stores variables, functions, objects, etc that would make them able to persist or be shuffled around. /jw
