memory management primitives availability in 4.2BSD

[Doug Gwyn <gwyn>]

The proposed 4.2BSD memory management syscalls were not provided
with 4.2BSD.  Word was that the code had been written but failed
on VAX-11/750s due to problems with the firmware.  Supposedly the
latest DEC ECO was supposed to fix that, so a future release of
4.nBSD can include this facility.

If you can't find this code anywhere and get really desperate,
consider using UNIX System V shared memory facilities.  Of course
that involves yet other trade-offs and so may not be acceptable..
