It would also have to be a new 4.4 branch as it breaks binary compatibility for extensions.

    It is far from being usable in mainstream as it relies on various

    a requirement for being accepted into the repository.  I
    suppose the patch authors are aware of that which is why they
    have not come forward yet.

    Sascha,

    Take a look at the code, the C is fully portable.  Computed gotos
    are completely #ifdef'd out, meaning that if you don't compile with
    gcc we could built it with a switch() loop.

Guys, We're not going to have major changes in the 4.x branch. We'll look into each of the changes and decide whether to incorporate it into ZE2. Some of them are good (like the cached zval allocation and saved calls to copy_ctor/dtor) and some of them are not so good (like the lookup caching for variables), and some don't apply to ZE2 (like the computed gotos). Sebastian - I think the fact that Sterling and Thies didn't raise it here was intentional (could be wrong, though). Zeev
