%% TODO MARK: Hrm, the intermittent failures of both of the tests
%% in machi_cr_client_test.erl were due to this func returning 0.
%% But machi_flu_metadata_mgr_sup:init() doesn't make a child with N=0.
%%
%% The remaining puzzle for me, which I'm now punting to you, sorry,
%% is why those two tests would sometimes pass, which implies to me that
%% sometimes the code path used by those tests never chooses worker 0
%% and occasionally it does choose worker 0.
