New submission from Gregory P. Smith: The implementation of string interning uses a dict [1]. It would consume less memory and be a bit simpler if it used a set.
Identifier strings in a program are interned. If you have a large program with a lot of code, this makes for a large dictionary. Experimenting with changing this to use a set on 2.7 found ~22k savings on an interactive interpreter startup. Measuring it on a huge application showed a few hundred k saved.
