I've been going through the .16 to .17 changes.  I don't actually think
the expunge callback stuff is the problem, but I can't seem to reproduce 
the problem people are seeing either.  www.php.net seems to be running 
smoothly on 3.0.17.  See http://www.php.net/~rasmus/apc.php

So at this point I think the strategy should be to take the .16 code and 
only apply the bug fixes and the removal of the local cache stuff and 
push out a .18 based on that.

It's 7am in Bangalore right now, so Gopal should be coming online in a 
couple of hours.  He was playing with stuff last night, so let's see if 
he has found something.
