I've recently made changes to Timer to allow TimerTasks to be reused so that a TimerTask can reschedule the same object
into the future without a lot of garbage being generated for fast cycling tasks with odd repeating intervals. I think
it makes a lot of sense to try and work towards reducing garbage generation by not requiring new objects. There are, of
course some interesting issues, such as this one...
