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

[michail alexakis]

Hello Atilla and thanks for your response!

Unfortunately, i dont have the option to deploy under the GAE or use any
GAE-specific libraries.
There is a way to force the openid.Server instances to be thread-local but
this won't be adequate
if the storage level is not functioning in an thread-safe manner.
Well, my question had more to do with the openid.Server being inherently
safe, i.e. managing to
maintain all it's state in a isolated thread-safe store.

Kind regards, Michail
