---------------------------------------
BTW, test run is taking 100s for me: too long
{code}

I'm going to to strip it down
* downgrade single part upload test to uploading a few tens of bytes.
* remove reverse test, leaving only reverse non-contiguous
* test of abort to upload fewer blocks first
> Add specification of Multipart Upload API to FS specification, with contract
> tests

> There's nothing in the FS spec covering the new API. Add it in a new .md file
> * add FS model with the notion of a function mapping (uploadID -> Upload),
> the operations (list, commit, abort). The [TLA+
> mode|https://issues.apache.org/jira/secure/attachment/12865161/objectstore.pdf]l
> of HADOOP-13786 shows how to do this.
> * Contract tests of not just the successful path, but all the invalid ones.
> * implementations of the contract tests of all FSs which support the new API.
