I think that I could run some stress tests (say, like the exhaustive
regression tests that the ntfs-3g developers use), just to get some
basic functionality on HFS+ working.

Thanks once again, Andrew.

Just to make it clear: the reason why I loop-mounted the filesystem was
just to work with a low-risk situation and submit the image to the
recently "ported" fsck, just to get a little bit more confidence that I
didn't mess with the userspace side of things.

But, then, this surprise.

I had some minor inconsistencies with the HFS+ driver in the past, but
they were fixed by running the fsck.hfsplus that I packaged and I didn't
bother reporting it before. My mistake. :-(

Thanks, Rogério Brito.
