What about tasks that null out data members at the end of the execute 
method to release objects that are no longer needed (on the assumption 
that the task is one-time use only)?

My point was basically that certain tasks might support being reused, but 
as a general rule I wouldn't try it; I've seen many tasks that make the 
assumption that they will only be used once.

Bottom line - I would assume it's not safe to reuse a task unless I was 
certain that the task was coded in such a way to allow that type of usage.
