I think cancelling tasks should be as specific as the cancel request, as in ``def unschedule(self, name, args=None, kwargs=None)`` - ``name`` is compulsory, but match is restricted by ``args`` and ``kwargs`` if they're present.  This is on the assumption that if you want to cancel a task, you know enough about the task to cancel that specific one.
