    If I were to give advise here, it would be 'don't worry about the
    peformance cost of doing a fork()'.

Oh, sure. I just also wanted to avoid having to have a process running all the time. Right now every dma instance cares about itself and does all queueing, etc. Once it has done its job, it quits.


Running a setuid root binary or having root starting a setuid process doesn't make much of a difference, no?
