I'm surprised that you didn't include:

This comes up from time to time, but to me it is very blurry how this 
can work in reality.

Considering how "shared" is supposed to be used to be useful (do some 
locking, then cast away "shared") there is no guarantee by the language 
that any object is actually thread local (no references from other 
threads). Working with immutable (e.g. strings) is shared by design.
