[boost] [asio] how detect deadline_timer expired state?

I'm performing an async_wait() on a deadline_timer.  Based upon some
independent event (e.g., a keystroke) I want to [re]set the timer and,
if it was expired, 'fire' an event indicating that the system has
changed state from not_running to running.

Maybe I'm missing something obvious, but it seems that deadline_timer
should have a method to test whether or not the timer had expired (i.e.,
bool expired() ).

BTW: This library is a joy.  When does the review period start?  ;)
