  10                 ^   ^                |            |

  17 Changes are made in working tree 1, and made available to Linus.  Linus
  18 merges them into his tree.  I fetch them into the pristine tree.  Assume
  19 other changes occurred. in Linus' tree.
  20
  21 The pristine tree is obviously a superset of the working tree.
  22
  23 One example of a problem arising from this - after one round, objects which
  24 first appeared in working tree would be overwritten with the same objects
  25 but with newer date."
