Well, I must admit, that a problem was with different loop variables set. One var (whereshared_ptr
was used) had one ZERO more in its decimal value.... What a shame! Sorry guys! But I am happy now.

Now with default macros used, shared_ptr is about 10% slower. If I use the quick allocator the
speed is only 8% slower. If I enable both macros (single-threaded and quick-allocator) shared_ptr
is quicker as an implementation without shared_ptr. My question now would be if you plan or it is
already possible to have a policy for specifying Threading and Allocator?
