[issue5084] unpickling does not intern attribute names

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

Why do you call PyString_AsString() followed by PyString_FromString()?
Strings are immutable so you shouldn't neek to take a copy.

Besides, it would be nice to add a test.
