Does "that" refer to using tests_require=['tox'] as I described below? This
means using easy_install implicitly and being exposed to easy_install
bugs.  Note that my attempts to avoid easy_install so far led to dependency
hell starting from the need to install virtualenv.  Unlike setuptools, pip
does not seem to be able to install dependencies in a temporary directory.
It wants a full-blown venv tree.
