Hmm... hadn't quite thought of it in those terms.  The locking_ptr<> need 
only contain two members, a mutex and a scoped_lock, and the proxy would 
hold a reference to the scoped_lock.  A little dangerous because this shares 
the lock object across threads... but the idiom may be made to work.  Then 
the question remains, are there other examples/use cases where the lock must 
be locked in one scope and unlocked in another where a similar idiom won't 
work?

I guess for now I'm going to table this until other examples can be found.
