   If you are refering to -current and NOT -stable, then it's caused by a bug
in the DEVRANDOM changes and was just fixed by Bruce. Otherwise I really have
no idea since there haven't been any commits in this area or even related
areas. In fact, there have only been two or three commits in the past week and
they have nothing to do with this...
