Larry Hastings added the comment:
And to further confirm, on my Linux machine with a ZFS partition:
* stat() returns nanosecond resolution.
* I have utimensat(), which supports nanosecond resolution.
* The test code correctly sets "utime.now = 1", so it correctly calls
utimensat() with a time pointer of NULL.
It still fails, but here the race is much closer:
before: 1407191476502407010
after: 1407191476502090829
before <= after False
If I run the test on a different filesystem (e.g. on /tmp which is ext4) the
problem doesn't occur.
My guess: it's ZFS's fault in both cases, it's not using the highest-precision
timer available.
