Re: [libvirt] [PATCHv6 9/8] blockjob: allow speed setting in block copy

Paolo proposed 'drive-mirror' to upstream qemu prior to Stefan Hajnoczi's patch to 'block-stream'. qemu 1.1 has included Stefan's patch, but Paolo's is still in limbo, and needs to be rebased if it will even make qemu 1.1. But it is a logical extension to assume that when Paolo rebases his drive-mirror patches, that he will also add an optional 'speed' parameter; so as to avoid the same data race as was just fixed in 'block-stream'.
