[...] Sorry to be blunt, but i dont think there's a different way to say it: i am a user of the software you are maintaining (Qemu) and i dont think you have the basis to educate people about what a good maintainer should do to achieve a quality end result. I think you could/should learn much from Linus and others who very much require quality to permeate the full dimension of a contribution (including usability), beyond the narrow, local scope of the contribution.
