It is in the beginning of this thread, before it changed name. Search for the subject containing "Virtual memory question" from around January 11th. The original subject lives on in brackets. The first message-id is <20030111224444.94D102A89E@canning.wemm.org>, and there is quite a bit of elaboration afterwards. > > Actually, we dont care for the shm_open() API too much at all since it > > conflicts with our application libraries. > > Too bad.

And we'll probably remove it from RELENG_5 if we ever use it. Matt's stuff is relatively easy to backport. We wont be backporting the shm_open() API stuff ourselves.
