all Mac Python versions.

\subsection{dnr result object}
Since the DNR calls all execute asynchronously you do not get the
results back immedeately. In stead, you get a dnr result object. You
results back immediately. Instead, you get a dnr result object. You
can check this object to see whether the query is complete, and access
its attributes to obtain the information when it is.
