[[!tag btree]]
I pushed out release version 0.9 of my B-tree library. Mostly optimizations, and a fix for one bad performance-related bug.
I'm starting to feel carefully optimistic about this B-tree. It is still too slow, being able to do only about 1700 inserts per second on my laptop, but I'm not done working on it yet.
(Patches welcome! Bug reports, too.)
