    I am not so interested in performance optimizations, but do I think
    offering time in nanoseconds is attractive from an application point
    of view. The timespec is impractical for everyone.

    While you are at it with new syscalls, why not make a clean break from
    POSIX and fix the uglies?

    - New name, to distance ourselves from POSIX (clock_ns_get?)
    - Family of calls, with set/get
    - Sub nanosecond field
    - TAI time base (or according to parameter?)
