ok, if you pull that branch now i've added some random files, so you can run e.g.:

time PYTHONPATH="$(pwd)" python3.6 -m pex.bin.pex --with-fingerprinted-inputs=demo2.json --remote-component-cache-baseurl='<https://secret-url.io/home/pex/v1.6.11+with.incrementalism/components>' requests -vvvvvvvvv --no-compile --no-use-system-time -o lol.pex
