The Executor classes are horribly buggy.  Pool size adjustment, idle 
timeouts, and shutdown sequences do NOT work.  Some of the features are 
impossible to implement efficiently so Sun instead chose to implement 
them incorrectly.

For an Executor, it would be more correct to iterate through all the 
Future or Callable objects returned and ask for their result.
