It hasn't, but the case being discussed doesn't involve multiple 
(simultaneous) owners. The behavior of the original enable_shared_from_this 
is well defined when there is a single owner; the behavior of the Boost 
implementation was also predictable when there was no owner. (It's undefined 
in TR1, though.)
