Awesome. I plan to do a new release for this in the next couple of days.

Interesting idea, but I don't think it's worthwhile. It looks like this is only a noticeable improvement if size is 10 or 1, and I don't think these are common cases (especially not for users who care about performance). Also, I'm reluctant to have two copies of the code for _read_block(); it makes the code harder to read, and increases the chance of introducing a bug when changing the code.

Of course. I'll apply these optimizations to LZMAFile next weekend.
