      Bug#39951 Falcon: crash during crash recovery.
      
      The problem is that in Database destructor, tables are accessed
      deep in systemConnection->rollback(), at the time all Table objects
      have been freed. Crash reason is accessing freed memory.
      
      Solution is to cleanup system connection before Table objects are
      freed.
