Review Comment:
   I made this change as we were making minor changes when larger refactorings 
are done in earlier PRs, and calling those minor changes in the PR. 
   Sure, we can keep this PR only for renames. But I do not think we should 
have a contract for the caller to invoke in a lock because we have a volatile 
primtive to be incremented. This can be discussed in another PR.
