This question has come up a number of times before.  It appears the  
jail will only go away after all resources associated with that jail  
are returned.  Unfortunatly, there doesn't seem to be an easy way to  
identify which resources are still allocated to it...

We're running one 5-stable box with 7 jails, and so far, those  
phantoms have all disappeared eventually.
