Well, I've heard of that problem, but I'm not sure it really exists.

1. I've profiled the bisocket code without finding any leak.

2. When java.util.TimerTask.cancel() is called it sets its "state" variable to "CANCELLED".  Now, java.util.TimerThread.mainLoop() does this:

  |                     task = queue.getMin();
  |                     synchronized(task.lock) {
  |                         if (task.state == TimerTask.CANCELLED) {
  |                             queue.removeMin();
  |                             continue;  // No action required, poll queue again
  |                         }

so the first time the cancelled TimerTask gets run, it should be removed from the java.util.Timer's queue.

3. BisocketSocketInvoker will recreate its Timer if the Timer has shut itself down, but the reference to the old Timer would be lost, so the old Timer should get garbage collected eventually.

If I'm wrong about anything here, or if I'm missing something, please let me know.
