Good point. It will in the usual case:
shared_ptr( detail::shared_count const & pn, Y* px );
which I admit I had in mind.
It won't if we use
shared_ptr( detail::shared_count pn, Y* px );
and swap(pn,pn_) as poor man's move.
Let me bring up something else. Should
shared_ptr(Y* p, D d);
call sp_accept_owner(this, p), or should it call sp_accept_owner(this, p,
&d'), where d' is the stored deleter?
