Description: 
We found a few unit tests, but nothing that exercises Gossip under challenging 
conditions. Maybe consider a long test that hooks up some gossipers over a fake 
network and then do fault injection on that fake network. Uni-directional and 
bi-directional partitions, delayed delivery, out of order delivery if that is 
something that they can see in practice. Connects/disconnects.

Also play with bad clocks.
