Hi Phil,
What exactly are you measuring here? The time taken to construct an
std::auto_ptr<T>/std::shared_ptr<T>/block_ptr<T> inclusive of the time
taken for ::operator new(std::size_t) and inclusive of the
value-initialization T::T() ?
Yes but it also calls ::operator delete(void *) and T::~T().

If I don't use fastblock<>() then it's a simple 150% speedup compared to 
shared_ptr<>:

new:
auto_ptr:                   22279670 ns
shared_ptr:                 47428316 ns
block_ptr:                  31287440 ns

My point with fastblock<>() is that it can be use very easily because it 
is already integrated.
