utils.py: Try harder to extract good traceback information by querying the datastore
Currently as soon as execution passes outside the code fragment being
executed by better_exec, we don't get any good traceback information,
just a likely obscure reference to some function name which may
or may not be identifiable.
This patch adds code to query the datastore if present, allowing a more
meaningful back trace to be displayed in many cases.
