[Boost-users] weak_from_this

shared_from_this contains a weak_ptr.  Why not implement a
weak_from_this() member function?

Upgrading and downgrading a shared_ptr costs expensive atomic ops.  I've
got some setup code that just gives weak_ptr's to
boost::singals2::slot::track().

Is this a valid (and simple) feature request?
