1.10.x

continues to fail shard 3: https://travis-ci.org/pantsbuild/pants/builds/439800324, i've blasted caches and restarted three times. unclear how this happened, since it looks like when the change was made it passed CI? (https://travis-ci.org/pantsbuild/pants/builds/434363409 passed on the first commit of https://github.com/pantsbuild/pants/pull/6568)

./pants test tests/python/pants_test/backend/python/tasks: -- -vs -k pex_resolver_blacklist_integ

should also fail on your machine. i'm trying to pin other versions but i'm not finding i'm able to figure out why this suddenly stopped working. i also ran

rm -rf .cache dist .pants.d build-support/pants_dev_deps.venv ~/.cache/pants/python_cache ~/.pex

and tried again and it still failed
