I do not believe it is possible to do so with just an allocator under
C++11. :-(  I think the best one can do is have a separate (not embedded in
the allocator, and hence, not embedded in vector) arena for the space, as
in http://home.roadrunner.com/~hinnant/stack_alloc.html.  So there is still
a need for a static vector class.
