Ouch. While it's an interesting way to deal with the issue, I think this will be way too slow, and maintenance will be hard (keeping up with changes in the real zend_execute, and zend engine in general). As in a couple other responses, the way this needs to be implemented has been hashed out, largely based on how the same problem is solved in Perl (there is a remarkable amount of simularity between PHP and Perl at some levels).
