I worked on erl_mock in order to publish my spike around mocks in
erlang. When I was almost ready to make the package, something interesting happened: my tests failed.
More precisely, they failed when run by the ‘future’ version of extremeforge.
After the first surprise, I find the reason. Extremeforge use 2 nodes,
the first one will find, order [...]
