    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?
