若运行策略等于 std::launch::async 且实现无法开始新线程(该情况下,若运行策略为 async|deferred 或设置了额外位,则它将回退到 deferred 或实现定义的策略),则抛出以 std::errc::resource_unavailable_try_again 为错误条件的 std::system_error ,或者若无法分配内部数据结构所用的内存,则为 std::bad_alloc。

1) 可能抛出 std::system_error,它的 std::error_condition 在线程没有创建条件变量的权限时等于 std::errc::operation_not_permitted,在某项非内存资源限制阻止这此初始化时等于 std::errc::resource_unavailable_try_again,或者等于其他由实现定义的值。
