It would probably be possible to initiate an AddToBlockIndex or Reorganize after the check, but it would require a lot more careful attention. I probably should break out part of AddToBlockIndex that sets the new best block. I'll probably end up doing that instead of the code below.
这就是我最后在 SVN rev 139 里做的。
This is what I ended up doing in SVN rev 139.
我没有删坏链，而是给 ConnectBlock 加了一个额外的 CheckBlock，这样坏区块一旦被踢出去就回不到最佳链了。
Instead of deleting the bad chain, I added an extra CheckBlock to ConnectBlock so bad blocks can't get back into the best chain once they're kicked out.
