The module entropy_path_loader (used only for running from within the checkout; otherwise not even installed) is made to provide the _entropy namespace. (Other ideas instead of this entropy_path_loader change would be to reorganise files layout; drop support for running from the checkout as is - and perhaps require virtualenvs; require sourcing a script that sets PYTHONPATH. However, as implemented, it is not intrusive, and the good part is that it is quite isolated, not used in normal usage after installation. Basically, it only does sys.path + provides _entropy namespace.)
