KIO's KDirListerTest::testRefreshRootItem on RHEL7 and XFS

[Jan Kundrát]

Hi,
there's one test in KIO which keeps failing when I run it inside my CI 
environment (a RHEL7 VM with XFS).

Take a look at [1], the /tmp/kdirlistertest-dIp2zR/subdir's mtime and atime 
are getting bumped by one second. The patch which introduces this debug 
output is at [2].

I will admit that I'm not sure what that test is actually testing -- I 
would have expected some sort of file watcher in the background, but I'm 
not sure with the manual calls to org::kde::KDirNotify::emitXYZ. Anyway, 
the comments on lines 401-402 seems to indicate that the sort of behavior 
I'm seeing is semi-expected.

What can I do to fix the test failure I'm seeing? Why is the change of 
/tmp/kdirlistertest-dIp2zR/subdir encountered "too early" in this test?

With kind regards,
Jan
