Because if you retry binding to the same socket fast enough, it'll fail. Even from the same process (after unbinding). There's some sort of timeout in place.

OTOH if you were to always use an ephemeral port 0, the kernel would allocate you a different port each time and there wouldn't be such a problem.

Sorry, I confused. I misread as SO_REUSEPORT.

- Fixed 'deflate' compression. According to RFC 2616 now.
  `#4506 <https://github.com/aio-libs/aiohttp/issues/4506>`_
- Fixed OverflowError on platforms with 32-bit time_t
  `#4515 <https://github.com/aio-libs/aiohttp/issues/4515>`_

  `#4562 <https://github.com/aio-libs/aiohttp/issues/4562>`_
- Always make sure transport is not closing before reuse a connection.

  Reuse a protocol based on keepalive in headers is unreliable.
  For example, uWSGI will not support keepalive even it serves a
  HTTP 1.1 request, except explicitly configure uWSGI with a
  ``--http-keepalive`` option.

  Servers designed like uWSGI could cause aiohttp intermittently
  raise a ConnectionResetException when the protocol poll runs
  out and some protocol is reused.

- Make `web.run_app()` more responsive to Ctrl+C on Windows for Python < 3.8. It slightly
