That's pretty much what Linus suggested. He proposed having a new syscall interface which was just calls into the magic page. All syscalls would thus be available via the magic page. The kernel could then selectively optimise individual syscalls (like gettimeofday(2)) or optimise the interface into kernel space, without libc ever having to know about the details.
