Agreed it's a problem, but probably a small one. At worst you'll get

Presumably this would be bad for soft-realtime embedded things. Set-top
boxes, etc.
SCHED_RR/FIFO are not affected. AFAIK it's only used by the interactivity
detector in the normal scheduler. Worst case that happens is that a
process is not detected to be interactive when it should once, which
gives it only a small penalty. On the next time slice everything will be ok again.
Other problem is that some people didn't RTFM and have started trying to
use it for precise accounting :(
