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.
