It appears to be a BUG!
When a job is 'moved' to a new queue the new job 'control file'
does not have appear to have the 'move' field in the 'control file' cleared.
I will check into this and fix this up.
Symptoms: if you look at the 'read' and 'write' calls, you will find a 'move=...'
appearing in the values read or written. This should not be the case if the
control file is for a new job or when moved to a new queue.
