And I couldn't but notice that the test had passed this time ...
So I tried to re-run it from "make check", and passed this time as well.
Weird. Let's see if I can reproduce the failure with:
$ i=0; while strace -o ut ./test-utimens; do echo RUN $((++i)); done
... Well, I still haven't reproduced it after 47 runs. I'll let you
know if I manage to reproduce it somehow. In the meantime, I've taken
the liberty of tagging my report with "moreinfo".
