syscall numbers are just arbitrary descriptors, on which the kernel and
libc have to agree. That is all. No policy involved. If you say "Thou
shallst not use syscall <insert favorite syscall number here> unless thou
art root" _that_ is policy. Set by POSIX, in this case, _not_ the kernel.

Then I won't repeat mine ;-)

No policy involved here either.
