Are you sure this is the case for btrfs? Mike Hommey has described the sync() implementation as really horrible[0] (unfortunately the webserver on glandium.org is currently down, but the Google cache[1] has a copy). For ext4, mounting with the nodelalloc option helps a lot, although this option allegedly slows down ext4 in the general case.
