I read a variation on this theme some years ago that uses 
event.wait(timeout=delay) to manage the delay.

>From the docs, "block until another thread calls set() to set the flag to 
true, or until the optional timeout occurs."

The benefit is that setting the flag terminates the loop straight away, as 
opposed to waiting for the sleep to finish.

I can show some sample code if anyone is interested.
