Er... as long as you don't have more than 50 active sessions at once  
(which doesn't seem all that many if they're long lived).
If this is really the only way to reliably deploy (it's not a problem  
I've personally had, but it seems like enough others are), then we  
really need to find a way to reclaim memory within a session, maybe  
even explicitly, that doesn't rely on WeakArray.
