I don't see anything in glibc that does this. Have I missed something?

i think you're correct.  the code in glibc atm is merely a syscall().  i think 
the idea was to have the C library guarantee that and if moving forward the 
kernel changes, the C library would update by adding a wrapper.  maybe just 
drop this sentence until that day comes ?
