Research direction

The issue names split, merge, confchange, and the kvstore lock but provides no files, tests, or implementation details. Start by locating those operations and their lock handling in the repository, then determine how to shorten the lock hold time without changing their behavior. Done means the operations hold the kvstore lock for a shorter period, with relevant tests still passing.
