would be nice if we waited for cryptohome here.  I would think every test would
want to be started when chrome really is up and ready.

waiting for cryptohome is no guarantee that Chrome is up and ready.  In fact, we
wait for a file that's output by an upstart job that runs when
start-user-session is emitted on Chrome's behalf -- something that happens
strictly after the cryptohome is mounted.

would be nice if we wait for the login manager here - just in case another
client test is starting soon after this that expects the login manager to up.
