I myself have done so in a [project](https://github.com/jb2170/SocketCat/blob/73d3bf4f30bfb1ad6e3b2710cc3a7586b5d1499c/src/SocketCat/common.py#L14).\r\n\r\nThese classes seem to have been overlooked because they require two `if` checks for `hasattr(socket, \"AF_UNIX\")` and `hasattr(os, \"fork\")`.\r\n\r\nIt seems clear to me therefore that these two classes should be added to the `socketserver` standard library module\r\n\r\nSome people prefer forks to threads\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-103674\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/jb2170","@type":"Person","name":"jb2170"},"datePublished":"2023-04-22T01:40:42.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/103673/cpython/issues/103673"}
