- this is v0.63 so it's not a stable release
- it's not clear whether this is backported or not to 0.61
- i cherry-picked the relevant commits together with a guy from inktank 
and it was working with v0.61 but it has still some bugs like finishing 
rbd command before the image is really deleted...
- it speeds things up but with multi terrabyte stuff it still needs a 
lot of time
