/**
 * This class invokes a callback function after a certain amount of
 * time.  Use Schedule() to start the timer or Cancel() to cancel it.
 *
 * Unlike #CoarseTimerEvent, this class uses a high-resolution timer,
 * but at the cost of more expensive insertion and deletion.
 *
 * This class is not thread-safe, all methods must be called from the
 * thread that runs the #EventLoop, except where explicitly documented
 * as thread-safe.
