Comment:

 Yes, as you noted the copying ensures the object lives as long as the
 thread.

 If you need to use a large, non-copyable object you can either use a
 pointer (as in your example), or use boost::ref:

 foo large_object;
 boost::thread t(boost::ref(large_object));

 If you do this it is up to you to ensure that the referenced object
 outlives the thread.
