public class SingleShotLinearTimer
extends java.lang.Object
This class provides a very stripped-down clone of some of the functionality in
java.util.Timer (notably Timer.schedule(TimerTask task, long delay) but
uses System.nanoTime() rather than System.currentTimeMillis() as a measure
of the underlying time, and thus behaves correctly if the system clock jumps
around.
This class does not have any relation to TimerTask due to the coupling
between TimerTask and Timer - for example if someone invokes
TimerTask.cancel(), we can't find out about it as TimerTask.state is
package-private.
We currently just use this to time the quiescing RPC in AMQChannel.
