Recursive zval patch for review/comments

Hi, I'm not quite sure about this patch. But this does bring back up apc speed to pre recursive-zval levels. http://t3.dotgnu.info/code/recursive-zval-mk2.patch And somehow seems to fix a relatively random, but recurring coredump (more on that on monday) with apc-cvs right now on centos+apache1+x86. I'm not quite sure of this patch - i.e is APCG(copied_zvals) allocated in every scenario which could have a recursive alloc, is my assumption about IS_ARRAY check before hitting copied_zvals right, etc. Therefore, I'd like a couple more eyeballs on it - just to check sanity, at least.
