The forked companion manager inherits the arbiter's HTTP listening sockets, its wakeup pipe, and the worker heartbeat files, none of which the manager uses. Close them in the child before running so the manager and the companions it forks do not pin the arbiter's fds. The manager creates its own signal pipe and control socket after the fork.

Fork Information
--------
This is a fork of gunicorn with the following changes:
1. Request timeout implementation for `gthread` - https://github.com/frappe/gunicorn/pull/1 (upstream doesn't have any, we NEED this.)
2. Higher timeout for `selector` - https://github.com/frappe/gunicorn/pull/2 (This is a small optional performance improvement)
3. https://github.com/benoitc/gunicorn/pull/2918 is reverted to avoid connection resets while draining or restarting a worker.
Note to anyone upgrading/adding changes:
- Pull upstream changes
- Reapply our changes or reconcile our changes
- Update commit/ref in frappe/frappe `pyproject.toml`
- Keep this readme up-to-date with changes. Keep changes small and to the point.
TODO:
- [ ] Plan a cleaner solution using custom workers. All current changes can be used with custom workers but they have the same awkwardness of maintaining a fork since we want to "override" not extend core behavior.

Gunicorn 'Green Unicorn' is a Python WSGI HTTP Server for UNIX. It's a pre-fork
worker model ported from Ruby's Unicorn_ project. The Gunicorn server is broadly
compatible with various web frameworks, simply implemented, light on server
resource usage, and fairly speedy.
