If I try out the latest modifications and I disable the threads then on 
Linux I have:

make:
auto_ptr:                    2458626 ns
shared_ptr:                  2685224 ns
block_ptr:                  28300624 ns

new:
auto_ptr:                    2383605 ns
shared_ptr:                  4992185 ns
block_ptr:                   7979659 ns

Thanks,
