--- Comment #11 from Ben Widawsky <ben at bwidawsk.net> ---
I think Guo conflated the issue. The numbers reported can't be higher than the
actual time slept, regardless of clock granularity. Okay, if you round up
sometimes, it can be off by a little, but the amount we're off is actually
huge. 

In other words, what Guo reported in #5 is likely just that, approximation
error which can easily by fixed with a tiny bit of math to give some amount of
fudge in the positive direction. However, the original numbers that Wendy
reported aren't multiple reads, there are exactly 2 reads, and the application
completed in exactly 0m10.002s. I don't believe this explanation for the 1.14


real 0m10.002s
user 0m0.000s
sys 0m0.002s
BEFORE = 1281484
AFTER = 1292928
DELTA = 11444
1.14
