    the /proc/xxx/cpu file for this process looks like this:

    cpu 385220 202
    cpu0 207779 47
    cpu1 177441 155

    a while later:

    cpu 399219 204
    cpu0 214922 48
    cpu1 184297 156

    i.e. it keeps changing cpu's. Is this normal? I thought we preferred
    to keep a process on a single cpu.

    Cheers,
    Stephen
