[Python-Dev] Free threading

(Thick French accent:) "We already got one!"

In the C API, use PyThreadState_GetDict(): it returns a per-thread
dictionary.  The convention is that you pick a key unique to your
extension module (e.g. your full extension module name) and then store
your per-thread data under this key.

In Python, you can store instance variables on the current thread
object -- use threading.currentThread() to access it.
