Yep... For the record, we don't use any of this right now, and I doubt
that building with it defined would work at all. In the old days,
the scoreboard was implemented as a file; we added mmap() and shmget()
later, but always kept file-based around. What we do now is use
shared mem exclusively, whether it maps to a file or not. The 2
are very different :)
