Session (...) has been closed #204

memcachedClientBuilder.setCommandFactory(new BinaryCommandFactory());

用Binary模式的时候，如果传入的 key 
大于memcached服务器的key最大长度时（默认250）, 
不会报超出key长度的错误，而是直接报 Session (...) has been 
closed 。。。。

用text模式时会正常报错

恩，这是个bug，二进制协议本来应当允许key长度任意，但是me
mcached还是限制在255字节了。但是xmemcached却放开这个限制。

目前来说，你应该避免这么长的key，也可以利用1.3.8提供的Key
Provider对key做截断或者md5 hash。
