The SpanFlusher subprocess can crash during startup due to Redis connectivity issues, but the main consumer thread continues to wait in _wait_for_process_to_become_healthy() for a healthy signal that will never come. This makes health check function in the main thread determine if the subprocess is alive or has already been terminated to fail faster.
