You can easily wait yourself, and everyone would want to wait 
differently, so there is no point in putting into the queue's 
implementation.
For instance you could give up your scheduler time-slice, or you might 
want to spin-lock

while(!queue.pop(my_data))
{
       boost::this_thread::yield(); //give up time slice
}

//tight waiting

while(!queue.pop(my_data))
{
     //spin
}

Boost lockfree seems to be header only, but I'm not so sure about its 
dependencies.
Maybe someone can drop in here.
