	XSynchronize (dpy, 0);
    or
	XSetAfterFunction (dpy, (int (*)())0).

    What is the preferred way?

Either way is fine.  Note that both of these functions return
the previous after-function, so another way to undo is to save
the previous value and then store it back with XSetAfterFunction.

    Why is this not documented?

Because no one noticed that it wasn't documented until now.
Thank you for pointing it out.
