I've looked into the code closely again. The patch is heavily reworked since GSoC state :)
Tests are looking fine and locking is fine-grained.
But there is one thing I could not understand:
Why do we take a lock during moveRightIfItNeeded()?
This place is supposed to be called whenever page is split just before we a locking it and right after we've come to the page from parent.

Best regards, Andrey Borodin.
