As a dirty alternative, it is possible to have the thread object
wrapped in a structure. You allocate the structure on the heap and put
that into the container. Since copying of pointers is cheap, you do
not incurr the overhead of copying in STL containers. However, you
need to free up the memory during clearing the container.
Or, even use the BOOST shared pointer, I have not used this though.
