[boost] Re: smart pointer delete parameterization

In addition to Michel's thorough summary here is a description of 
deallocate:

    void deallocate(pointer p, size_type n);

Requires: p shall be a pointer value obtained from an allocator which 
this Allocator is capable of deallocating.  n shall equal the value 
passed as the first argument to the invocation of allocate which returned 
p (unless a specific instance of Allocator is known to relax that 
requirement).

Effects: Deallocates the storage referenced by p . 

All n T objects in the area pointed by p must be destroyed prior to this 
call.
