Even though v5 was posted earlier today, it was worth a respin:

The new test is rather slow (nearly 90 seconds for me using
tmpfs) unless it skips entirely (such as testing on ext4); ideas
for speeding it up are welcome (translation: maybe qemu should
optimize the search for the next available cluster to allocate,
and/or qemu-img check should be faster at reporting leaked
clusters)
