I'm curious what aspect of virtualenv you find "too heavy?" Disk space
usage? Mental overhead? Something else? (I create and dispose of
virtualenvs freely, often on the order of ten or twenty in a single
days' work, some of which don't live more than a couple minutes - so
they don't feel "heavy" at all to me.)

This isn't necessarily true (depending of course on what "heavy" means
to you). Tox is a quite simple and convenient tool for repeatably and
automatedly testing a project under a variety of Python versions (and
possibly other factors as well). The fact that it uses virtualenv is
pretty much an irrelevant implementation detail to the user; you never
see or touch a virtualenv yourself.
