* This is worth a comment to explain that this is called to handle any task created by shutdown functions or destructors, and to handle destructors that didn't return yet.

  Possibly this should be executed between php_call_shutdown_functions() and zend_call_destructors() as well, so that destructors are not called before tasks created by php_call_shutdown_functions() are executed.
