Thank you for 7.1.1! This release is now working perfectly for
me! I am excited to try out the multicast stuff now.

I dug into this some more. I was able to reproduce it, but I now
know why you couldn't. It was, in fact, not actually introducing
corruption but somehow re-delivering files that had been sent a
day or two ago. Why, I have no idea. How, I also have no idea.
Where, I don't know either. But once those got flushed out of the
system, everything was fine. No more dupes so far.

grumble grumble about ZFS's error message "cannot receive: failed
to read from stream". I eventually was able to verify sha256sums
matched, and then turned on zfs receive -v for verbose mode... and
the error was basically attempting to receive a snapshot that was
already present. It was an old nncp-file packet that somehow got
re-delivered and re-processed, and the same went for all the
others also.

I am sorry to have sent you on the wrong chase for that!
