Log message:
    Up to now, SerializableSnapshot and QuerySnapshot are malloc'ed and
    free'd for every transaction or statement, respectively.  This patch
    puts these data structures into static memory, thus saving a few CPU
    cycles and two malloc calls per transaction or (in isolation level
    READ COMMITTED) per query.
