paul lalonde's request is a good one, but i think a useful qualification is that it should also be shown in practice to have a reasonable implementation on several agreeably different architectures. one of the reasons mmap is bad is that like job control it whacked some vague ideas into an existing system without reference to its existing conventions, then vaguely extended it in a vague way from time to time, vaguely different from platform to platform, and with vague documentation. ``could they be any more vague?''
