Handling of hang in one branch of pipeline

[Federico Zamperini]

If I understood correctly, you can put an identity element in each 
branch and handle the "handoff" signal in the bus, which is posted every 
time a buffer is passed on.
You have to setup a couple of timers to trigger an alarm when no buffers 
are passed for a certain amount of time.
Or otherwise look for some other similar signals from the elements that 
are most inclined to hang.
