Measure aggregate throughput on the bottleneck link
Start all sources at time 0
Move queue_fh to a more appropriate location
Comment out printfs
Add back tracing; confirmed underflows with low resume threshold
Full N*N mesh of long-running TCPs
Fix memory leak in  DestHashClassfier
Remove "send 10000"; pointless because you want long-running flows
Allow lossy behaviour to coexist with lossless
More turnkey way of turning on or off pause
Ensure simulationTime < 1.5 till seq # wraparound is fixed.
Print out some useful debugging information
