Review Comment:
   Well I think we can keep both approaches, the weak ref trick can still be 
useful.
   
   Also, what would be really awesome is to have a test for this. Maybe 
adapting the code that was used to detect the leak in the first place? FYI we 
have a `SessionLeakIT` class that runs in isolation, so we can get crazy there 
and create 100 sessions if it's necessary. (Although, it's probably enough to 
create just one session, close it, then assert that the registry becomes empty 
again within some configured timeframe.)
