Thanks. I've seen a much worse case of this with the same UUID values,
but different MAC addresses..

There is a long history behind this, but yes, it sounds reasonable to
allow this. I don't exactly agree with this being an "improvement" of
overlap detection, but well, that is easy to change for the commit
message ;-). I have actually looked at working around the worse case in
the past and just had to gave up there. That's why I wanted to make sure
this is a smaller subset of the issue and something that can actually be
resolved without completely disabling overlap detection.
