    Re .4:
    
    Microsoft gave a short presentation on the 64-bit capabilities of
    Windows NT 5.0 while I was at the Professional Devo's Conference.
    NT 5.0's 64-bit support will only include a limited number of new
    system calls to read/write/copy memory using 64-bit addresses; the
    existing system calls will not change in NT 5.0. *
    
    This is in contrast to the "whole new version of NT" which is being
    developed for P7 which (apparently) WILL change the O/S to be based
    on 64-bit APIs.
    
    * My notes from the PDC regarding 64-bit support:
    
    Promoted as Very Large Memory (VLM)
    Maximum of 32 Gb of virtual memory; the standard 4 Gb, plus an
    additional 28 Gb with VAs from 4Gb to 28Gb
    Limited APIs to access the VLM area; alloc/free, commit/reserve,
    	read/write, sharing between VLM addresses
    No paging of 64-bit addresses (they didn't want to re-write the
    	paging subsystem)
