If you print __name__ in second.py its value is '__builtin__', because
of that your "main" doesn't execute.
Try adding this to test_exec.py before the execfile() call:
globvars[ '__name__' ] = '__main__'
It looks like a ad hoc fix but i couldn't find any doc about the change
of __name__ to 'builtin' of a python script being run
from another with execfile().
Regards.
