libcore.io.ErrnoException: kill failed: ESRCH (No such process)

这个问题遇到不止一次，记下解决方法备忘。   
运行稳定性脚本时框架崩溃，打印的堆栈信息如下：   
libcore.io.ErrnoException: kill failed: ESRCH (No such process)  
at libcore.io.Posix.kill(Native Method)  
at libcore.io.ForwardingOs.kill(ForwardingOs.java:77)  
at java.lang.ProcessManager$ProcessImpl.destroy(ProcessManager.java:257)  
at sogou.test.agent.framework.sysinfo.CMDExecute.run(CMDExecute.java:29)

查看了异常发生的位置CMDExecute.java:29，是：   
            if(process!=null)\{  
             process.destroy();  
            \}

发生崩溃的原因log里说的很清楚，就是被destroy的进程已经不存在了。

解决方案：   
将    
            if(process!=null)\{  
             process.destroy();  
            \}   
换成    
   try \{   
            if (process != null) \{   
                // use exitValue() to determine if process is still running.    
                process.exitValue();   
            \}   
        \} catch (IllegalThreadStateException e) \{   
            // process is still running, kill it.   
            process.destroy();   
        \}    
 exitValue()函数采用非阻塞的方式返回，如果没有立即拿到返回值，则抛出异常。
