That doesn't work.  As near as I can tell now based on my experiments
and reading, my problem is that I am attempting to launch the tests via
an automated ssh connection from another computer.  SSHD on Cygwin does
user-switching, but only gets Windows auth tokens if you use your
Windows password to login.  Since I can't use a password with ssh from
an automated script, I cannot get Windows auth tokens, and without
Windows auth tokens, Windows won't let me see or mount, _any_ network
share, not even a share that allows anonymous connections.
