Perhaps then that phase of the test shouldn't be considered complete?

In a netperf TCP_STREAM or TCP_MAERTS test, the test isn't over until 
there is an indication the last byte has arrived.  As such, what one 
might request to be a 30 second test can end-up with say a 34 second 
elapsed time.  That is I suppose along the lines of your proposal C.
