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。
