When building from same stream all nodes need to read data from the same stream. In order to achive that there is a new SyncMultiReader wrapper that sends the stream concurrently to all readers. Readers must read at similar speed or pauses will happen while they wait for each other. Dockerfiles were already written to disk before sent. Now the file written by first node is reused for others.

I was wondering if we could have integration tests for this. I think we could have one similar to Line 66 in 8411a76 docker-container:// protocol?
