python3.6.7 ::优雅地处理RuntimeError错误

Question

是否有一种优雅的方式来处理错误，因为这会掩盖实际的RuntimeError错误

async def clean_up_process_wrapper(app):
    while app.is_running:
        await(sleep(0.1))
        try:
            await asyncio.gather(*[system_object['start_cleanup_process'] for system_object in app['State_Machine_Container'].values()])
        except RuntimeError:
            pass
