Comment (by kevan):

 attachment:393status7.dpatch contains minor modifications to the
 downloader that cause the last two seemingly related tests to pass. For
 whatever reason, tests that test the bucket counter and lease crawler
 sporadically fail -- I didn't touch that part of the code, and I'm not
 sure why the parts of the code that I did touch would cause those
 failures, but I guess that's software. I'll look at that after I get some
 tests written. Also, the mutable slot proxy now allows callers to tell it
 how to batch requests. This is helpful in the case where we want to fetch
 a block, salt, and the parts of the block hash and share hash trees
 necessary to validate those things from the remote storage server, since
 it allows for us to do that in one remote read operation with four read
 vectors. There is also a test for this behavior.
