"gr_osview" uses the standard System V structure sysinfo, which is 
"documented" in the header file /usr/include/sys/sysinfo.h.  The structure can
be conviently read using the sysmp(2) call, which has a man page, and uses
the /usr/include/sys/sysmp.h header file.  This avoids having to read the
UNIX namelist and read from /dev/kmem, like standard SysV does.  There are
other interesting hooks in sysmp(2), some of which gr_osview uses.
