Gary Benson: Python atomic counter

Do you need a thread-safe atomic counter in Python? Use itertools.count():

>>> **from itertools import count**
>>> **counter = count()**
>>> **next (counter)**
0
>>> **next (counter)**
1
>>> **next (counter)**
2

I found this in the decorator package, labelled "Atomic get-and-increment provided by the GIL". So simple! So cool!
