There's another problem with your new implementation, one that wasn't caught
by esft_regtest (I updated it to catch it):
boost::shared_ptr<V> pv( new V );
boost::shared_ptr<V> pv2( pv.get(), null_deleter() );
Your implementation modifies pv2.
This ease with which one might inject subtle failures in remote code (such
as Boost.Python, incidentally) makes me think that sp_accept_owner is a bit
too dangerous. Maybe its shared_ptr argument needs to be made const. This
would break the new constructorful esft though.
