Oh, I see now that it also happens with something as simple as
function foobar () end
add_input_event_hook ("foobar");
so the problem is generic, and probably not the fault of the ftlk
callback taking too much time.
So Jacob, I think you should use the input_event_hook mechanism to
handle your callback.
