 I think I understand. A concrete example might help me and others
 understand better.

 It sounds to me as though this is unlikely to cause a practical problem
 for users of Tahoe-LAFS v1.9.0.

 As an aside, I think the bigger picture here is that the "robustness of
 upload" semantics are too complicated for users (or even for *me*!!) to
 understand what the intended result is, much less to understand what the
 intended behavior is, much less to understand what effects the deviations
 from that behavior (bugs) have. Kevan's project to unify mutable and
 immutable upload semantics and to fix the bugs in his Servers Of Happiness
 semantics are a step in the right direction, in my humble opinion.
