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)?

Well, bravo for venturing a possible implementation, but I'm not versed
in Apache or PHP internals to propose or evaluate one in that kind of
detail :(. 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.
