System V Shared Memory

[Roland McGrath]

Neal did something on this before.  Look through the bug-hurd and
hurd-devel archives for "System V Shared Memory" (or just google for that
plus hurd).  I think the conclusion of that was he had a proposal that used
existing filesystem calls to implement almost everything.  I don't recall
the details at the moment, but digging them up and reviving the discussion
would be a good thing.  I don't think there is very much work involved in
making it all work.
