I must admit that if we don't plan to do pool allocation for the reference
count, the the bigger shared_count object is virtually free, since a block
containing single long typically consumes about the same amount of memory as
a block containing a long and three pointers.

But I don't like adding the additional layer unless it pays off either by
significantly reducing cut and pasted code between shared_array and
shared_ptr or providing additional features.
