Comment:

 Daira says that this branch has the same problem that Servers-of-Happiness
 had for static (immutable) files — #1382. That problem is that the upload
 strategy is not designed to achieve optimal happiness (it isn't the Upload
 Strategy Of Happiness), but then after the upload strategy has done its
 work, then the Servers-of-Happiness criterion is applied to it, which may
 cause that upload to be marked a failure.

 Having looked at [https://github.com/markberger/tahoe-lafs/tree/1057
 -mutable-servers-of-happiness the branch], it looks plausible to me that
 it does have that problem.

 Daira and I think this ticket should be moved out of Milestone 1.11 and
 into Milestone 1.12.
