I think copy _0 timed out (and hence the "terse" log) and copy _1 was really close (less than 1.5 hours) before timing out. Maybe something activated when Running in High Priority and seeing that it wouldn't finish on time.

Edit: P.S.: I like the word "hence", that has been used extensively in this thread

When I started banging' out messages, it was on teletypes across the internet's predecessor(s). Although I've grown both verbose and pedantic since (partly a function of increasing communications speed and capacity, no doubt), I still haven't lost my general preference for the shorter word when choosing among synonyms that was driven by having to change paper and ribbons. An idiosyncrasy that was exaggerated one late night when I undoubtedly abused my powers and had various and sundry entities patch up a circuit that went from the teletype on my right out through nations to my west, went around the world, and came back to the teletype on my left (I was facing south; the direction of flow seemed to make sense).

And was subsequently vastly amused by the fact that I could type a sentence on the teletype to the west, then give the floor a kick and scoot my chair down the panels and be in front of the eastern teletype before that sentence started coming in. The propagation delay introduced by equipment and distance only increased my preference for interesting short words that at least gave the appearance of bearing more information in smaller containers - of greater efficiency, that is.

Consequently, hence. (And, of course, I am easily amused.)

At least I quit using "thence"; although it is definitely shorter than "from there to", I decided it was too much of a good thing...it generated too many "Is that a word?" queries. It seems to have been relegated to the emergency cache of Scrabble players.
