    Research direction

    Start by running the attached socket_sigint_sigbreak.py reproducer on Windows and confirming the SIGINT behavior during recv. Then trace the relevant Python socket and signal-handling entry points; done means the reproducer no longer leaves SIGINT blocked by the socket operation, with regression coverage for the reported case.
