In our case, we always send complete chunks.  At the point where we 
decide to send a chunk, we have some data, and we know its length, and 
we have decided to send it.

So the signal it would always fall on the start of a new chunk, e.g. we 
scan, determine the content to be malware, and so the next chunk sent 
would be 0 and signal an abort due to malware.

A close would then be less ambiguous, since nothing explicit was 
communicated, the client could then more reliably assume it was a 
transient network error.

I can't really think of a requirement to abort part way through a 
chunk.  Not in this scenario anyway.

If the intermediary is re-chunking then it can easily get around this issue.
