It is on NTFS, but we're separated from it by at least CIFS server and
client implementations.

The time stamps were identical in all combinations:
1) Local VM filesystem (ext4).
2) vboxsf.
3) cifs.
a) sync ();
b) sleep (10);
c) sleep (0.1);
Maybe the bug is only triggered when we're editing an existing file?
