Guest time can be unreliable, it could also indicate that Linux

I think the C flag change should only increase performance. The next
commit may have negative effects because more work is done every
interrupt, but it's also more correct now.
Hmmm looks like you're right. I did a few more tests measuring wall
clock time and averaging across a set of runs gives roughly the same
time (although there does seem to be quite a bit of variation in
resulting times on my system here). So nothing to worry about here.
