-/* Implementation Notes:
- *
- * PHP stores scripting engine state in thread-local storage. That means
- * that we need to create a dedicated thread per-engine so that a host can
- * use more than one engine object per thread.
- *
- * There are some interesting synchronization issues: Anything to do with
- * running script in the PHP/Zend engine must take place on the engine
- * thread. Likewise, calling back to the host must take place on the base
- * thread - the thread that set the script site.
