    I don't think so. They're independant processes, and I insist on reducing
    their X work in order to ensure they don't get perturbated by external
    factor. Their work consist in looping 250 ms and waiting 750 ms, then
    displaying a new progress line.

    It may indicate some special handling of nice ?

    OK, I will restart from fresh 0.45 and try again.
