Description
This test adds empty documents with no field contents, then reopens and asserts that scores are the same. Its not supposed to be a random test, it just does a simple execution against each query.
But it fails with this seed in trunk (i committed some improved debugging):

This is scary, it means the first reopen did not make documents visible when it should have? (or there is a sneaky test bug)
