That's right.

You needn't bother to submit a patch that breaks it ;-).  But I don't
really see that it's such a big deal.  You just need some state data to
keep track of what to do the next time you receive a message.  There's
no assumption anywhere that authentication only involves one message
exchange.

Correct, we don't need to worry about multitasking apps there.
