Maybe. I guess it takes some measurement to see if it is actually 
needed. For one, the container will allow you to do

   boost:.auto_buffer<T,N> buffer( n, boost::dont_initialize );

to make it avoid initialization. Futhermore, you may use

   buffer.unchecked_push_back( x );

to avoid code that checks for a full buffer and subsequent expansion.

If that is not good enough, then why not just use boost::array<T,N>?
(that is, if you really never will need the heap for any n)
