you don't, tho I was stunned to see compile and execute (assume using 
namespace std here):
ostringstream ost;
ost << 5 << " abcdefghijklmnopqrstuvwxyz";
string widget;
widget.swap(ost.str());
cout << widget << endl;

do what I hoped...

cout << ost.str() << endl;
afterwards still had the original buffer, so I guess str() returns a 
constructed copy of the buffer;
