Returning duplicate rows while using cursors

When using the cursor in the Get-Object-PDU request to obtain data from a
command responder, there might be rare situations where the command
responder might send back multiple entries for the same row. For example,
Subagent 1 might have registered for row X and Y and Subagent 2 might have
registered for Z.  If the retrieval starts at this point and if Subagent 1
unregisters  row X and Subagent 2 registers for row X, then the command
generator might receive two copies of row X.

There were different methods discussed to solve this problem. The real
question though was whether the cost of implementing the solution was worth
doing or if the command generators would be able to handle multiple entries
for the same row in rare situations.
