2nd example should work now (just did a commit), with the latest
updates Oliver Kowalke did on the threadpool lib.

ticker1 >>= ticker2 >>= ticker3 >>= ticker1 creates a cycle in the
network.  Hence, the signal will cycle through the network
indefinitely (it only stops because of the shutdown).

and comment on this example further.  Should be done later today.
