I have a question： the book <SQLite Database System Design and Implementation> chapter 4.2.2 says: A pending lock is always just a temporary stepping stone to the path to an exclusive lock.
is that mean when obtain exclusive lock success,the writelock at "pending byte" is unlocked ? anyone knows about it?
