That function calls `rb_mutex_sleep(wakeup_mutex, Qnil)`, waiting for `read_thread` to clear its blocking operation and signal the mutex. If `read_thread` doesn't properly wake and signal (e.g. due to GVL contention or scheduler interaction), the close task hangs and the test never reaches the `expect { read_thread.join }` assertion. -- This failure may therefore be a separate liveness issue in the close/wait handshake rather than the stale-interrupt problem in Failures 1–3, but both are triggered by the same `rb_thread_io_close_interrupt` / `rb_thread_io_close_wait` mechanism.
