   Nobody was quite sure how mmap `ought' to work, and it never got
   implemented....

.... in BSD. So those vendors who needed it, SUN and Sequent, implemented
it *differently*. Encore probably has another variation. I have used
both of the SUN and Sequent versions, and am not sure which I prefer.

On the other hand, everyone knows how munmap `ought' to work :-)

   System V shared memory is wrong.

Nice to know. I had always suspected as much. I think it will take
more than Bill Joy to fix System V.
