build_cloud(rand_shuffle=True) is default for now. it will randomly shuffle the flatfile we're creating in all cases, and separately shuffle a list that has the ip and ports for the jvms we're going to start. This effectively starts jvms in random order. rand_shuffle=False is the old scheme where the order for both is a nest loop of .. for hosts; for ports ...

Gut Paxos.  New simpler consensus building algorithm

Detects and builds a "cloud" - a cooperating group of nodes, with mutual
knowledge of each other.  Basically tracks all the nodes that *this* node
has ever heard of, and when *all* of the other nodes have all heard of each
other, declares the situation as "commonKnowledge", and a Cloud.
This algorithm differs from Paxos in a number of obvious ways:
 * - it is not robust against failing nodes
 * - it requires true global consensus (a Quorum of All)
 * - it is vastly simpler than Paxos
Cleanup inet byteordering
better hash function
more aggressive assert on the hash
Fixed race w/hashcode compute
added some stuff to h2o.py to make rm of tree (sandbox) maybe more robust in windows. hopefully didn't break anything. not clear if it really helps (h2o.py). The issue is well noted on 'net (removing directories with various windows-specific permission or other issues..

GLMScore test prints out a message saying it isn' working till we get the json response for GLMScore updated
