Fixed #20402: removed as-limit from uWSGI example.

        --processes=5 \                 # number of worker processes

        --uid=1000 --gid=2000 \         # if root, uwsgi can drop privileges

        --harakiri=20 \                 # respawn processes taking more than 20 seconds

        --limit-as=128 \                # limit the project to 128 MB

        --max-requests=5000 \           # respawn processes after serving 5000 requests

        --vacuum \                      # clear environment on exit

        --home=/path/to/virtual/env \   # optional path to a virtualenv
