0b88a12c16 WIP: Debugging cruft, egadz, but improving (see below) 
So, this still pops up occasionally:

    % rebar skip_deps=true -v eunit suites=machi_flu0_test,machi_chain_manager1
    [...]
    a private: [{epoch,223},{author,a},{upi,[a,b]},{repair,[]},{down,[c]},{d,[{author_proc,react},{nodes_up,[a,b]}]},{d2,[{up_nodz,[a,b]},{hooray,{v2,{2014,11,3},{20,19,57}}}]}]
    b private: [{epoch,224},{author,b},{upi,[b,a]},{repair,[]},{down,[c]},{d,[{author_proc,react},{nodes_up,[a,b]}]},{d2,[{up_nodz,[a,b]},{hooray,{v2,{2014,11,3},{20,19,57}}}]}]
    c private: [{epoch,191},{author,c},{upi,[c]},{repair,[]},{down,[a,b]},{d,[{author_proc,react},{nodes_up,[c]}]},{d2,[{up_nodz,[c]},{hooray,{v2,{2014,11,3},{20,19,57}}}]}]

The mis-ordering between [a,b] and [b,a] happens after the partition settled
on the islands of [a,b] and [c].

6ef46a3464 Temp WIP: I am going to sever the connection between the flowchart and the code. TODO 
That diagram is really valuable, but it also takes a long time
to make any kind of edit; the process is too slow.  This is a todo
item a reminder that the flowchart is important documentation and
must be brought back into sync with the code soon.
