Subject: [PATCH] Add [manual] test of kinit cmd

It's not ready to always be run.  First, it's slow.  Second, it tortures
the system.  Third, it doesn't look for signs of failure.  Fourth, if it
did it'd fail: because something about the racing is causing the KDC to
think that the foo principal doesn't exist.
