N1851 was not discussed in Berlin (lack of time). The status as
summarized in N1954:

stands as it was in Mont Tremblant. "Set in stone" is probably not
the right characterization. The C++0X working draft is just that, a
draft. We anticipate that it will continue to change. Defect
reports will be applied to it. Language changes that may be
introduced could have a large impact on the library portions of the
draft (e.g. bind could radically change if lambda functions are
introduced into the language). In part, getting items into the
working draft is to solve a logistical problem. We need a document
that we can read, edit and improve. We can't as easily create a
perfect document when large parts of it (that we know we want in
principal) are scattered throughout various papers.

We know we want shared_ptr or something very much like it. It may
mutate before standardization. But we feel its current specification
is sufficient for the working draft.
