tyrant自动忽略了flags参数
复杂对象缓存时是经过压缩的，同时flags参数变为1，再取出��
�tyrant忽略了flags参数。

这是tt特性决定的，两个方案：
1、使用KestrelCommandFactory，在每个value之前自动加上4个字节的f
lag，对应用来说是透明的，但是仅支持
set,get

2、自己实现Transcoder，在value前加4个字节flag.

1.2.1版本将添加一个TokyoTyrantTranscoder，在value前加4个字节flag��
�对应用来说处理是透明的

将你的测试代码发过来看看，我测试没有问题。

能不能将你的测试代码发过来看看。

已经经修复。
这个问题的发生是由于xmemcached的优化策略引起的，在多个相�
��key连续get的情况下，xmc内部
会优化成一个get操作，那么对于tt来说，这个优化会引起多次
decode同一个CachedData，每次
Decode都会改变CachedData中的数据，导致数据不正确，现已修正�
��并在1.2.4版本中发布。

1.2.4已经发布。
