I think so.

If this proposed patch is applied, then it's the opposite: if you remove
the port from Logical_Switch.ports, then the garbage collector will
automatically delete the Logical_Port object (because there are no
remaining references to it).


arosen - in that case I think we also need something that can ""remove element X from this column
(regardless of what's currently there)" otherwise we'll have the same problem in the delete case no?
