linux 循环脚本如何停止

[jeky_zhang2013]

最近在测试linux在低内存下的表现，在网上找了如下简单的方式：
脚本 usemem.sh : 内容如下
echo "unlimited recursive call..."
sleep 0.5
usemem.sh
我让上述脚本自动运行，在内存达到限值时，停止该脚本，过5秒再执行，现在的情况是脚本运行10S左右就死机了，请问如何停止该脚本运行，是通过程序，不是人工ctrl+C操作。
我在linux进程信息中看到到大量的/system/bin/sh进程,杀掉父进程，子进程也不会全部停掉。

why do recursive call? why don't u use loop while 1 if condition meets oops, out of memory. I will take care of it else sleep for couple seconds if you want to exit the script through an elegant way, you could put a signal handling method there so the script can do cleanup before exit...

多谢回复，请问等待一段时间能消耗内存么? 我试了循环只消耗cpu多些，对内存的影响不大
