When using ``gevent`` you might also want to set the ``_AIRFLOW_PATCH_GEVENT``
environment variable to ``"1"`` to make sure gevent patching is done as early as possible.

Be careful to set ``_AIRFLOW_PATCH_GEVENT`` only on the web server as gevent patching may
affect the scheduler behavior via the ``multiprocessing`` sockets module and cause crash.
