Hm. Is it? So construct() and destroy() would act as custom 
allocator/deleter?

Anyway, let's say that all allocation is done with the supplied 
allocator via rebind<>. This is what you require to use ptr_container 
with monotonic allocators, right?

But how do you get objects into the ptr_container in the first place?
Do you intend users to write

  container c;
  c.push_back( c.get_allocator().construct( 
c.get_allocator().allocate(sizeof(T)) );

?

And how do you pass constructor arguments to construct?
