Thanks for the reply.

this issue really came up in a conversation elsewhere.  The point made to
me was that leaving the growth strategy completely up to the implementation
is a flaw in the design of the STL.  In situations where memory is critical
and
efficiency is secondary a vector becomes unusable or at best implementation
specific.
