I'd like to start a new thread with Gregory's suggestion
and my comments.

Boost already has boost::allocator.  IMO other boost libaries
should consider using boost::allocator instead of 
::new and std::allocator.

I'd modify it to 

* Consider parametrization if your library is to be available 
  for embedded or non-traditional platfroms.

I'd add to it
* Follow boost::allocator specification for allocator parameters

$.02

$.02
