Description
warner wrote in ticket:1398#comment:6 :
publishing immutable when the file is already uploaded: our Uploader doesn't short-circuit the upload when it discovers that enough shares are already in place. The upload sequence runs (including encryption and erasure-coding of each share), but the results are discarded. (this is arguably an inefficiency, but I'm not convinced the additional code paths would be worth it). So the memory footprint is the same as for not-already-uploaded
