Bug description:

On Fedora Linux 44, the built i686 debug Python 3.15.0a1 fails the test.regrtest, as test_sendfile times out:

test_sendfile (test.test_ssl.ThreadedTests.test_sendfile)
Try to send a file using kTLS if possible. ... kTLS is available
Timeout (0:45:00)!

Research direction

Start with Lib/test/test_ssl.py, especially ThreadedTests.test_sendfile and its read/run helpers, and reproduce test_ssl on the Fedora i686 debug build. Read the corresponding Lib/ssl.py read and recv paths shown in the timeout; done means test_sendfile completes without timing out on the affected configuration.
