# It is likely that we'll run a Python script somewhere in the final app. By default, Python will buffer lines print()ed to STDOUT / STDERR, and they might end up in container's log after a delay and with a wrong timestamp (e.g. log messages). So, disable such buffering altogether to all containers by default.
