There is a public C API starting in 2.5, the progression for sets was
pure-python in 2.3, C in 2.4, and polished in 2.5 after it was better
understood how people use them.  If Hettinger is around he'll correct me
if that explanation is off.

There are people that use sets from C-code but I don't know if they use
the slotted methods, the 2.5 version, or a special build.
