* Attempt to prevent the deadlock in the QueueDiskChannel Test again This time we're going to adjust the pause tests to only test the right flag. * Only switch off pushback once we know that we are not pushing anything else * Ensure full redirection occurs * More nicely handle a closed datachan * And handle similar problems in queue_channel_test Signed-off-by: Andrew Thornton <art27@cantab.net>
