I checked the password table on *.194, and sure enough, the password was not the hash of "ome". One of the other tests had changed the password.

We can add a changePassword before the execution of the examples in order to rollback any changes, but this is only a partial fix; this may break other tests (though that is fairly unlikely), and also does not fix the underlying race condition. In general, each section may need to be started with a different user to prevent this from happening.

It's not clear whether this is even still valid and it needs real investigation in order to be adequately addressed. Closing as invalid, we can re-address this going forward.
