What steps will reproduce the problem?
1.执行redploy或者shutdown操作时，发现应用服务器无法停止，进
程依旧存在.

What version of the product are you using? On what operating system?
1、xmemcached 1.4.1
2、Tomcat 6.0.36
3、OS：Window 7 32bit
4、Memcache 1.2.6
5、扩展了Spring 
cache，从而支持采用memcache做缓存实现，使用@cachable注解

以下是详细的错误信息：

从日志看，用了springframework。在关于MemcachedClient的bean销毁时�
��者spring的容器关闭时，执行一下MemcachedClient的shutdown，即可�
��免这个异常的抛出。

1.4.2 
released，将reactor设置为daemon线程，应该不会出现这个问题了��
