    The inline spinlocks are _wonderful_ for seeing where the contention is in
    a simple profile.

    In contrast, in a profile the out-of-lines ones will show "x% was spent on
    spinlocks". Which doesn't help much when you want to see where the problem
    is.

    This was _hugely_ useful, at least for me, for seeing what locks were
    problematic.
