      <p>
        Memory is now allocated incrementally as needed, instead of all at
        once during environment initialization, for structures that support
        locks, transactions, threads, and mutexes.  With this change new
        functions have been added that configure how much memory is
        allocated initially, and how much that memory is allowed to grow.
        The old memory configuration functions have been deprecated.
