Comment(by kevan):

 I'm uploading the new tests. I'll need to modify them again when we define
 a way to give the Encoder more information about which servers have which
 shares.

 It occurred to me when writing that test that my patch to Encoder doesn't
 do what I thought it did when I wrote it. Specifically, since
 self.landlords in an Encoder is simply a list of IStorageBucketWriters
 (I'm not sure what I thought they were, but it wasn't that), doing
 set(self.landlords) doesn't really do anything (let alone give a good
 value for the number of servers that are left). So I need to think of a
 better way of doing that, too.
