 * gjs_runtime_destroy:
 * @runtime: a #JSRuntime
 *
 * Calls JS_DestroyRuntime() on runtime and frees data allocated by
 * gjs_runtime_init(); these are unified into a single call because we
 * need to order things so that the allocated data is cleaned up
 * after JS_DestroyRuntime(). We might have finalizers run by
 * JS_DestroyRuntime() that rely on the information stored in the data,
 * such as the dynamic class structs.
 *
 * This should only be called by GJS, not by applications.
