[Code] Fwd: python-openid server thread-safe methods?

[Attila-Mihaly Balazs]

Hi,

We are using the python openid on GAE with the threaded python27 runtime
and we didn't see any problems with it. We use the gaecache.MemcacheStore
as store and a separate instance of openid.Server per thread (using
threadlocal).

Regards,
Attila
