The hardest thing about that is figuring out the defaults. Setting the
shared memory segment size being the primary thing. But if a reset in ZO
is low-overhead, I suppose setting a conservatively low cache size isn't
going to cause too many problems. With APC because of its memory
manager, once the segment starts to fill up things start to slow down a
bit as it ends up spending time hunting for free blocks to use.

Also, if we are going to turn it on by default I'd really like to get
rid of zend_optimizerplus.inherited_hack and zend_optimizerplus.dups_fix
since they are both quite hard to explain to users and hit things a user
really shouldn't have to concern themselves about. With the integration
we should be able to convince the compiler to give us op_arrays we don't
need to have hacks for here.
