    SubjectRe: [PATCH] hrtimers: Special-case zero length sleeps
    Regardless of whether userspace should be concerning itself about this 
    kind of thing or not, there's plenty of userspace that calls sleep(0) on
    the assumption that it'll get rescheduled. This makes using whole-system
    timer slack difficult, because there are some applications that do this
    even if they're event-driven and sleeping for significant lengths of
    time here breaks them. I'd certainly understand the argument for fixing
    userspace instead, but that's a massive task for something that's easily
    special-cased in the kernel.
