  23. Tandem's Guardian system has had this capability for about 12 years.
  24. Each file has an attribute that says whether updates to that file
  25. belong to transactions.  This transaction manager existed long before
  26. relational databases a la SQL became popular; we implemented SQL as
  27. another object manager using the same transaction manager.
