> It may be easier to identify what causes error commands to be returned on an exec if the command is included in the error message. this can be done with
> * a toString() operator on the class that includes the list of arguments (when non null)
> * a test that this works with arguments with spaces, and a null array
> * relevant use of the operator when an execute fails, such as in TaskTracker
