This happens when status opens a db betweeen two of the many
transactions that form an update, one that creates a workqueue item
and one of which removes the workqueue item. Status sees the
workqueue item and produces that message. In the past with multi-db
this could happen part way through a status operation, whenever a db
was opened. Now in single-db it can only occur at the start of the
status operation. Since the update is still running it will continue
and clear the workqueue, so a subseqent status might not produce that
error and no cleanup is required.

I'd like status to continue, rather than produce that error message,
perhaps indicating the presence of a workqueue item with 'Q' instead
of, or in addition to, 'L'. I suppose there is a possibility that
status would misbehave if we did this, although 1.6 didn't appear to
have a problem doing this.
