I wonder how a sequence like

your::vector<int> v(/* filled some how */);

if ( !v.empty() )
{
   v.first();
}

could be implemented without a lock, and without a lock external to the 
container.

Lock-Free or Not Lock Free, I think that STL-Containers have a interface 
that is quit useless for beeing used in a threaded eviroment.
