process flips between CPUs

[Matthew Dillon]

    A process which is sleeping most of the time will tend to be scheduled
    on whatever cpu is available.  From the perspective of the scheduler
    which may switch between user processes on a 1/100 second clock a
    process which uses the cpu heavily will tend to be scheduled on the
    same cpu.  However, from the human perspective observing the top or ps
    output, even a heavily cpu-bound program will switch between cpus every
    so often.

    Normally locking a process to a particular cpu is not necessary.
