Can we make this MAP_INHERIT_ZERO (and provide MAP_ versions of the other ones, too)? OpenBSD and NetBSD use MAP_*, and there was discussion long ago about using the same #defines in FreeBSD (from before user-visible constants appeared in mman.h)
It would be nice to avoid needing compatibility #defines or #ifdef FreeBSD tests in all of the consumers.
