Yeah, I was using usecs_to_cputime(), believing this was the standard 
interface. By the way, one of the things that also led to better results
were just forcing it to 0 every time we had steal == 1 in the end. But
*that* was a real hack =)

What do you think about keeping accounting in msec/usec resolution and
(thus allowing us to compute half a tick to user/system, other half to
steal time) only change it to cputime in the last minute?
