--------------------------------------------------------------------
[~sergey-chugunov] Hi! The problem is:
* [1] needReplaceInner = TRUE, locking the tail up to the inner node, set to
READY
* mergeEmptyBranches fails because of concurrent operations, releases tail for
retry (doesn't change needReplaceInner)
* [1] needReplaceInner != TRUE, so we don't lock the tail up to the inner node
* [2] replaceInner can't find inner in the tail
Sorry for not providing this info earlier
(oops, comment race)
