Stamps, versions, ordering

[Eric Dean Tribble <tribble>]

What you're looking for is predecessor/successor/unrelated in the context
   bert's history.  Before/after is meaningless if they don't share a timeline.
   (Much like relativistic events outside each other's light cone, and you can
    never trust time stamps.)

   Don't we have a less-than relation on tree-ordered history traces that does
   exactly that?

The tree ordering currently appears at a higher level.  It also will
only appear for stamps actually recorded in a historical trace.  I was
referring to something more like a timeline.  For any two Stamps
generated by a particular Bert, there is always an ordering of those
Stamps.
