    i'm certain that if you used a struct {} and filled in 3 fields rather
    than zeroing 64 bytes of memory, and doing 3 conversions to decimal ascii
    then you'd see a marked decrease in the overhead of this. it's not clear
    to me why you need ascii here -- the rest of the existing bsd accounting
    code is not ascii (i'm assuming the purpose of the fork connector is for
    accounting).
