Well, not quite -- we'd need to support sys_personality() if linux
emulation was in.

None of this sounds unworkable, and it would alleviate the current
pain a bit. Of course, if NetBSD went to ELF, we'd be stuck again.

BTW, if NetBSD does go for ELF, maybe we should go for a modified ELF
with a different magic number and OS identifiers?
