One extension to the allocator interface that I would like to see 
standardised is a global function std::initial_reserve() that can be 
overloaded by allocators to indicate to containers the initial size 
that they should reserve (the default version would simply return -1 
to indicate that the initial reserve size is unspecified).
 
This is essential to implement stack-based and other per-object 
allocators, for example see the stack_allocator class in the files 
section in "bjp_utilities*.zip" (this is a slightly older version 
that doesn't use exactly the proposed interface- I will upload an 
updated version soon).
