Here, we seem to have some cases where a write can occur but st_mtime is not updated before the next stat or fstat. I don't yet know how to characterize these cases, or how to work around them. Even Emacs's old approach (allow up to 1 second of slop) seems like it won't work in some cases that have been reported here: over 2 seconds of slop in <http://bugs.gnu.org/13149#115>, and over one minute of slop in <http://bugs.gnu.org/13149##100>!
Is is possible that the test is measuring something not directly relevant? Like I mentioned, emacs-24 build seems to work fine on cifs in all observable respects, but with this test, cifs has the slop of infinity. Or close enough.
