# https://github.com/unbit/uwsgi/pull/2615
# atexit should be called when reached max-requests.
#
# Start this app:
#
# $ ./uwsgi --http-socket :8000 --master -L --wsgi-file=tests/threads_atexit.py \
# --workers 1 --threads 32 --max-requests 40 --min-worker-lifetime 6 --lazy-apps
#
# Access to this app with hey[1]:
#
# # Do http access for 5 minutes with 32 concurrency
# $ ./hey -c 32 -z 5m 'http://127.0.0.1:8000/'
#
# Search how many stamp files:
#
# $ ls uwsgi_worker*.txt | wc -l
# 39 # should be 0
#
# [1] https://github.com/rakyll/hey
