process as over the limit when its time is >= to the limit rather than >
the limit. Technically, if p->p_rux.rux_runtime.sec == p->p_pcpulimit
and p->p_rux.rux_runtime.frac == 0, the process hasn't exceeded the limit
yet. However, having the fraction exactly equal to 0 is rather rare, and
it is not worth the overhead to handle that edge case. With just the >
comparison, the process would have to exceed its limit by almost a second
before it was killed.
