base 模式下个一个已经关闭的$fd发送内容会导致进程异常退出

[breath-co2]

用 BASE 模式启动，往一个已经close的连接上 send 内容会抛错后导致 worker 进程异常退出，而且不会自动重启进程，多进程模式下不存在这样的问题。

如果 worker 进程只有1个，则会 Segmentation fault: 11 后全部退出，错误内容如下：

[2016-08-08 17:54:30 *76970.0]  WARNING swReactorProcess_send2client: send[0] failed, session#1 has expired.
Segmentation fault: 11

如果有多个 worker 进程，则会报这样的错：

[2016-08-08 17:58:58 #77620.0]  WARNING swProcessPool_wait: [Manager]unknow worker[pid=-1]

swoole版本多少，我用最新的master分支代码进行测试无法重现。

[breath-co2]

php:7.0.8, swoole: 1.8.8，系统:mac

最新的1.8.9代码测试无法重现core dump
