  :issue:8653.

• Fixed :py:class:aiohttp.TCPConnector doing blocking I/O in the event loop to create the SSLContext -- by :user:bdraco.

  The blocking I/O would only happen once per verify mode. However, it could cause the event loop to block for a long time if the SSLContext creation is slow, which is more likely during startup when the disk cache is not yet present.

Miscellaneous internal changes

• Improved performance of :py:meth:~aiohttp.ClientWebSocketResponse.receive and :py:meth:~aiohttp.web.WebSocketResponse.receive when there is no timeout. -- by :user:bdraco.

  The timeout context manager is now avoided when there is no timeout as it accounted for up to 50% of the time spent in the :py:meth:~aiohttp.ClientWebSocketResponse.receive and :py:meth:~aiohttp.web.WebSocketResponse.receive methods.

  Related issues and pull requests on GitHub:
  :issue:8632.

• Fixed WebSocket ping tasks being prematurely garbage collected -- by :user:bdraco.

  There was a small risk that WebSocket ping tasks would be prematurely garbage collected because the event loop only holds a weak reference to the task. The garbage collection risk has been fixed by holding a strong reference to the task. Additionally, the task is now scheduled eagerly with Python 3.12+ to increase the chance it can be completed immediately and avoid having to hold any references to the task.
