Sorry for the confusion but the real benchmark of the pointers is:

unique_ptr (new): 47.7686
unique_ptr (make_unique): 46.8545
shared_ptr (new): 77.8261
shared_ptr (make_shared): 50.8072
shared_ptr (make_shared_alloc_noinit): 33.021
block_ptr (new): 69.6554

But block_ptr<> handles cyclic references as well.  I just thought you 
might be interested in this benchmark.
