Comment(by zooko):

 I didn't understand your proposed solution in comment:63 to my proposed
 problem in comment:53.  Doesn't your solution mean that if the uploader
 encounters the servers in the opposite order, ending with {{{s_4}}}, the
 server that has one copy of each share number, that the upload will then
 abort thinking that the "sufficiency number" {{{S}}} is a mere 1?

 If that's the case, then a test just like the second layout in your nice
 new {{{test_problem_layouts}}} but with the order reversed should fail.
