    We are pretty close though. On 300MHz UltraII we have now fork+exit+wait
    time around 100usec (that is fork 10k times per second), but I have ideas
    how to speed that up (and with 50usec we can do 20k times per second).

    On the other side, if I understood Davem's approach, the pids might get
    reused sooner, after 32K/NR_TASKS (just in the rare case one task_slot will be
    used for all the tasks forked), which is usually 64 times.

    Cheers,
    Jakub
