+ * Hooks are normally persistent so that they can be called
+ * across asynchronous processes such as delivery and poll
+ * processes.
+ *
+ * insert_hook lets you attach a hook callback immediately
+ * which will not persist beyond the life of this page request
+ * or the current process.
+ *
+ * @param string $hook

+ * @param string $fn
+ * function name of callback handler
+ * @param int $version
+ * hook interface version, 0 uses two callback params, 1 uses one callback param
+ * @param int $priority
+ * currently not implemented in this function, would require the hook array to be resorted
