11511	delay should not cause the second argument to be called if it's a function	chrif		"I see in this ticket:
http://bugs.jquery.com/ticket/8489
that delay will not have a callback as its second argument. Problem is if someone overlooks the doc and try to use it as a callback, it actually gets called anyway at the first dequeue:
https://github.com/jquery/jquery/blob/master/src/queue.js#L89
but not at the subsequent ones:
http://jsfiddle.net/KcXVv/1/

It can lead to code hard to debug. If it works the first time, you might think you got the arguments right and overlook the doc.

Maybe something like that:
