Right technically it would be possible. But in this case the segment is
created by 
the first php parent and therefore known to that process and it's childs but
not to any other 
php process spawned to by the fast_cgi processmanager.

But you are right my initial statement was misleading therefore read:
"since shm can't be shared beyond process borders."
As
"since shm - in this case - can only be accessed by the php process spawned
by the fast-cgi process manager and it's childs".
