vector<> can probably never grow to it's maximum size!

Forgot to add: even supposing that we want to deal gracefully with these
::operator new throws (pool_allocator is able to do that), in such 
cases, vector
is actually requesting only an handful of bytes, typically cannot really 
keep on
working if allocator::allocate returns less. This is *not* the situation 
that you
presented at the outset, in any case.
