I'd like to note, that I use qemu-img to backup snapshots of images.
This works fine, it's just so slow. Of my 24 cores only 1 is used to
compress the image.
It could be so much faster.

Bug description:
Feature request:
qemu-img multi-threaded compressed image conversion
Suppose I want to convert raw image to compressed qcow2. Multi-
threaded conversion will be much faster, because bottleneck is
compressing data.
