> A goal of this code is "support O(1) commits to S3 repositories in the presence of failures".
Implement it, including whatever is needed to demonstrate the correctness of the algorithm.
(that is, assuming that s3guard provides a consistent view of the presence/absence of blobs,
show that we can commit directly).
> I consider ourselves free to expose the blobstore-ness of the s3 output streams (ie.
not visible until the close()), if we need to use that to allow us to abort commit operations.
