OK, I haven't been that thorough.  So, I suppose the call will fail for
a combination of onlydir with a non-directory filename.

But we still need to inhibit open/close/access events from being used by
any client in order to fix this bug.  (Unless someone finds a better way
by looking more closely into the problem relating to processes. Though
filenotify.el does not use them and so it may not be worth it.)
