* meta_thread_post_impl_task:
* @thread: A #MetaThread
* @func: The #MetaThreadTaskFunc to invoke in the impl context
* @user_data: An opaque pointer passed to func
* @user_data_destroy: Function called when user_data is no longer needed
* @feedback_func: A #MetaThreadTaskFeedbackFunc to invoke with the result
* @feedback_user_data: An opaque pointer passed to feedback_func
*
* Post tasks to be invoked inside the thread impl context.
*
* The user_data_notify function may be called in any thread, and must be
* thread safe.
*
* The feedback_func will be called on the thread implied by
* feedback_main_contxext. Passing a NULL feedback_main_context implies the
* GLib main thread.
