    I'm not really interested in making predictions on which design has the
    greatest potential for pure performance, I'm interested in what is proven
    to work and does the job better than any alternative. Right now, for
    certain workloads, that's undeniably slab. So I'd disagree that slab is
    on its way out until another allocator is shown to at least have parity
    with it (at which time I'd become more interested in the cleanliness of
    the code, the debugging support, etc.).

    It's my opinion that slab is on its way out when there's no benchmark that
    shows it is superior by any significant amount. If that happens (and if
    its successor is slub, slqb, or a yet to be implemented allocator), we can
    probably start a discussion on what's in and what's out at that time.
