* if the object was a session object... however this code is actually
* correct because nssCKFWObject_Create will return a cached version of
* the object from it's hash. This is necessary because 1) we don't want
* to create an arena style leak (where our arena grows with every search),
* and 2) we want the same object to always have the same ID. This means
* the only case the nssCKFWObject_Create() will need the objArena and the
* Session is in the case of token objects (session objects should already
* exist in the cache from their initial creation). So this code is correct,
* but it depends on nssCKFWObject_Create caching all objects.
