# tox has an undocumented (as of 1.4.2) config option called "sdistsrc"
# which can make a run use a pre-prepared sdist file.
# we prepare the sdist once , then launch the tox runs in parallel using it.
#
# currently (tox 1.4.2) We have to skip sdist generation when running in parallel
# or we get a race.
