// poller returns a WaitFunc that will send to the channel every interval until
// timeout has elapsed and then closes the channel.
//
// Over very short intervals you may receive no ticks before the channel is
// closed. A timeout of 0 is interpreted as an infinity, and in such a case
// it would be the caller's responsibility to close the done channel.
// Failure to do so would result in a leaked goroutine.
//

            It will be closed if no further activity occurs. Thank you.
