bug#21668: 25.0.50; auto-revert-test failure on Fedora x86-64

The auto-revert-test test fails for me routinely.  Not always, though; it's not 
reproducible in general.  Attached is a sample log.  I don't want to spend time 
debugging this myself, but thought that whoever wants to know about this test 
failure should know about it.

I'll check when my health condition allows.

Best regards, Michael.

I couldn't reproduce it, and I don't have a clue yet what's up.

However, Bug#21313 indicates that some strange things are happening with
events, especially from D-Bus and file notifications. So I would wait
until that bug is resolved, and check then again with you whether the
problem still persists.

Best regards, Michael.

I've just committed a patch to auto-revert-tests.el, which fixes a
subtle bug likely related to this problem. Could you, pls, check?

Best regards, Michael.

I've run 'make check' several times now, with no problems.  Thanks.

Thanks for testing, I'm closing the bug.

Best regards, Michael.
