--------------------------------------------------------------------

[~jay.zhuang] two other things I noticed as far as the code goes
* The patch needs to be updated so that it applies cleanly to _trunk_.
* Some minor coding style updates are needed. I have left a comments on the [9988-trunk-onecommit-update2
| https://github.com/cooldoger/cassandra/commit/c5003812327d4475a7fb29f11686c13eeb50d693]
branch.

Let me know if you need a hand with either of these. I am happy to make that change as well.

> In many cases we have small btrees, small enough to fit in a single leaf page. In this
case it _may_ be more efficient to specialise our iterator.
