This test case manages to let qcow2 abort because its cache is used up
and it can't find free cache entries for new requests any more.

One patch in my posted queue fixes the useless ".000000" (and another
related bug where decimals are *missing*); just a heads-up.

Otherwise the series looks good, but my qcow2-fu is limited.

Fixed this locally to say $QEMU_IO instead of ./qemu-io. Unless there
are more problems with it, I won't resend a v2 but just include the
fixed version in the pull request.
