Some late nitpicking, sorry:

This is not an atomic counter, it's a thread-safe counter. And since
being thread-safe is rarely a bad idea, especially assuming someone
will manage to Kill GIL, I would just call it a "counter" or Counter.

(Of course, atomic/lock-free implementations are nice when possible.)
