Ok, I changed my mind again ^_^. Volatile attributes are shared across multiple sessions, which is not acceptable for my application.

So here's what I cam up with :
* 1 : Do not store references to a ZODBish object into a non ZODBish object
* And 2 : just pass the context as a parameter to all the non-ZODBish methods that need it. I Tried to avoid this in the first place (hence storing it as an attribute), but putting them in the session broke everything.

Cheers.
