    No, it grew constantly in presence of compositing activity under X by 512 8
    byte objects per second or more, possibly multiples of 512 or very close.

    If you haven't seen my original post, kmalloc-8 cache after some days of
    uptime looked like this:

    kmalloc-8 68044800 68044800 8 512 1 : tunables 0 0 0
    : slabdata 132900 132900 0

    I am now running 2.6.34-rc7 which seems not to leak.
