    I think Steven's machine (according to an earlier 'dmesg') has something
    like 384MB of RAM and just one PIII-450 CPU.

    With that setup, he's likely getting a lot of IO (and possibly even
    swapping). The BK disk working set for the kernel archive is something
    like half a gig per tree, I think.

    In contrast, your nicer machine will do the whole stress-test basically
    totally cached (well, BK will force writeback with fsync, but it will all
    be pretty synchronous with nothing else going on).

    So if it's IO-related or happens when swapping...

    But again, neither of those should usually cause that kind of strange
    partial-page corruption.
