那更多是 SelectCoins 层面的事。
That's going to be more of a SelectCoins thing.
SVN rev 161 有一个改进：递归判断你自己的未确认交易能否被花费。这是必需的，因你应该能立刻花掉自己的找零。
SVN rev 161 has a refinement to recursively determine if your own unconfirmed transactions can be spent. This is needed because you should be able to spend your own change right away.
新的递归判定是：0/unconfirmed 能花费，条件是它是你的，而且它的所有依赖要么已进区块、要么也是你的。
The new recursive determination is: 0/unconfirmed can be spent if it's yours and all its dependencies are either in a block or also yours.
这是一个 Windows 构建：
Here's a Windows build:
如果你已经有 0/unconfirmed 交易、而且可能已经花过它，这个版本是个改进。如果你是某笔 0/unconfirmed 交易的原始创建者，你仍然需要用 theymos 的补丁。
This version is an improvement if you already had a 0/unconfirmed transaction and might have already spent it. If you were the original creator of a 0/unconfirmed transaction, you still need theymos' patch instead.
