The task and all it's dependencies go away.  So anything dependent on it and the
things it depends on, are no longer dependent.

The task and it's dependencies remain, but nothing is executed.

The task is executed and does nothing.  (I believe this dumps a stamp file and
the noexec does not.. but I may be wrong.)
