Honestly, I think that making libc THE system interface is a mistake. Ok, I understand issues with the Linux approach of exposing raw syscalls (though it works well enough in practice and ossification could be amended by some kind of syscall versioning scheme), but why in the world can't you introduce libsystem/libsyscall/libopenbsd which would contain only "syscall" functions? Why do you need all the C junk in a library for talking with OS?
