I went about 200 blocks back.  The block chain was a clean straight line without branches, and there was only one known version of the locked block.

Sorry, not yet, but I do want to make the initial block download faster. --- Source file: bitcoin-forum-satoshi-nakamoto.tgz External link: https://bitcointalk.org/index.php?topic=437.msg3825#msg3825
