Serialize foreign-thread scheduling calls with the running loop in test_check_thread to avoid corrupting libuv state on free-threaded Python. Wait for the subprocess protocol connection_lost callback before asserting pipe shutdown stages.

Thank you for the PR! I added 3.15 in the CI matrix and fixed some more racing/flaky tests in freethread interpreters. |

Use cibuildwheel 4.2 for Python 3.9+ while retaining 3.2 for Python 3.8. Build and test macOS wheels on an Intel runner with native OpenSSL and native test dependency flags for universal2 builds.
Keep Python 3.8 on cibuildwheel 3.2 and use 4.2 for newer versions. Pair runners with architectures explicitly and test universal2 wheels on arm64. Prepare OpenSSL and Linux container dependencies for wheel tests, and pass the GitHub CI marker into Linux containers.

Summary
Keep the test-owned
epollwrapper on a duplicate of uvloop's backend descriptor. The loop retains ownership of its descriptor and closes it itself.This preserves the existing assertion that
remove_reader()removes the socket from the same epoll instance, while avoiding a second close afterloop.close()on Python 3.15.Validation

master:TestUVSockets.test_socket_sync_removepassesWhy draft
Current source builds and basic loop smoke tests on 3.15/3.15t, but this is only a test-cleanup prerequisite, not a claim of complete 3.15 support. The full 3.15t optional test dependencies are currently blocked upstream:
pyOpenSSL~=25.3.0resolves to cryptography 46.0.7, whose PyO3 build rejects Python 3.15 free-threaded. I will not add 3.15/3.15t CI or release-wheel targets until that complete suite can run green.
