After a make buildworld -j4


/kernel: calcru: negative time: -4668 usec
/kernel: calcru: negative time: -8424 usec
/kernel: calcru: negative time: -1238 usec

Is this a big deal?


Also..... calcru has a lot of nasty divides and mod's in it... How often is
this called? I notice getrusage uses it, anywhere else frequently?

Is the exact precision of 1000000 needed, or could a >> 20 do nearly the
same thing? Or is this something that's hardly ever used?

(Or, am I too used to dealing with a 68000's eternal divide times? :))

Anyone? :)

Kevin
