IMO, *any* performance degredation for this most popular environment
should mean that the patch should not make it in.

I know in the past we have been really reluctant to increase the zval
change. F.e. with the GC change we added bitfields. I think it might be
less of an issue now to increase the size, as Dmitry has I think
improved the allocator quite a bit, but it is by no means something that
should be glossed over lightly.
