qcow2_write_compressed in block/qcow2.c would need to be changed.
Currently it seems to need bigger changes as it always does compress+write for
one block.
Not sure, how well it would handle multiple writes in parallel, so the safest
would be to avoid that and just wait for the previous writer to finish before
starting to write.

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.
