Comment (by jaraco):

 Now I'm looking at this error:

 {{{
 src/allmydata/storage/immutable.py:205: error: 'BucketWriter' is missing
 following 'RIBucketWriter' interface members: abort, close, write.
 src/allmydata/storage/immutable.py:304: error: 'BucketReader' is missing
 following 'RIBucketReader' interface members: advise_corrupt_share, read.
 }}}

 Indeed, the RIBucketWriter and RIBucketReader [[https://github.com/tahoe-
 lafs/tahoe-
 lafs/blob/729a5a0779259303e8546bd60df454e55d12e975/src/allmydata/interfaces.py#L56-L72|define
 those methods]], but the BucketReader/Writer do not. Is that a feature of
 the RemoteInterface? What is the rationale behind this arrangement?
