关于安装MySQL5时的Thread Stack警告的问题！
本人在Fedora2上面安装MySQL5.01，在执行初始化脚本的时候有告警：Asked for 196608 thread stack, but got 126976
查看mysql的maillist中有不完全的解答：
This message is letting you know that the 192K thread stack was requested and it received about 125K.From my memory RH8.0 and other kernels needed about 128K to do core dumps properly so the
value was changed.You need to determine wheter this is a Problem for your configuration or not.
The value is to let you know what is happening.
大致意思就是应用需要192k的线程栈，但系统只能提供128k，请高手告诉我，这个线程栈有什么作用？怎样条件操作系统的这个参数以达到应用的要求！修改这个参数之后对操作系统本身有什么影响！
