Has to do with the ->refcount of every op_array.

It can't be free'd because free'ing it too early broke references in php user space. So it has to be done after every RSHUTDOWN is done and there is no hook for that.

According to <https://bugs.php.net/69618>, APC support has been
discontinued in favor of OPcache, APCu, the session upload
progress API and WinCache. Therefore this issue won't get fixed.
