Perhaps, but I still see no reason not to apply it. It may not help
many people, but it won't hurt anything, either. So why not?
More complicated, less tested code. For no practial benefit, it'll still
be slower than posix shm if there's any memmory pressure. But if you

In the same breath, it would also be nice if the following were committed:

Really? Why? According to the notes in our code, named POSIX semaphores
are the least attractive of the three Unixoid semaphore APIs

Meh. We don't put in effort into code that doesn't matter just

One of the patches that I've been sitting on and am derelict in punting
upstream is the attached mmap(2) flags patch for the BSDs. Is there any
chance this can be squeezed in to the PostreSQL 9.4 release?
The patch is trivial in size and is used to add one flag to mmap(2)
calls in dsm_impl.c.
