Thanks for reporting this.  Unfortunately they are known failures:

The precise leaked clusters number tends to change over time as qcow2
code is modified - for example, changes to the error code paths may
affect the leaked clusters in a particular scenario.

The output of the aio test is non-deterministic, I get a similar
"failure" here and it's simply a different interleaving of outputs -
the actual test is succeeding.

Fixing this is on my todo list and probably Kevin's too.  If you have
time to send patches, that would be excellent too.
