The only problem here is that I can't reproduce the assertion failure.

I created a Samba share on a Linux machine, mounted it as drive Z:,
and set the "always available offline" property of the drive.

After syncing I accessed the drive, then I stopped Samba on the Linux
server to switch the drive into offline mode.  Then I ran `ls -la
/cygdrive/z'.  After a few secs I got the offline content cached on the
local machine.  I also tried `ls -la /cygdrive/' and `cd /cygdrive; ls
-la', but every time I got the expected output.  In the cases I tried
to list /cygdrive itself I got the expected output, all drives except
the z drive.

I tried this with Cygwin 3.1.0-0.8.x86_64 on Windows 7 and Windows 10.

So either there's something very special in Wilfed's setup, or I'm
doing something wrong.  Which is it?
