test.test_asyncio.test_ssl often times out in Fedora ELN and EPEL 10.1 #142489
Description
Bug report
Bug description:
I noticed recently that in Fedora builds on x86_64, the test.test_asyncio.test_ssl test often (but not always) times out on Fedora ELN (next RHEL version) and EPEL 10.1. The failure often looks like this:
Re-running test.test_asyncio.test_ssl in verbose mode (matching: test_create_connection_ssl_1)
test_create_connection_ssl_1 (test.test_asyncio.test_ssl.TestSSL.test_create_connection_ssl_1) ... Warning -- Uncaught thread exception: AssertionError
Exception in thread test-server:

I don't know what's different in those environments, and I usually just retry until it succeeds, but recently it took 6+ tries for me to build Python 3.13.11 on EPEL 10.1.
I wonder if the timeout could be extended, or if this is some real problem :/
