Well, that'll teach me not to put in what went by, but I was so
incredulous myself at having seen it that I didn't catch it all.

"Oh, for a scrollable wscons!"

It looked kind of like

UNREF FILE I=NNNN OWNER=greywolf MODE=100644 SIZE=664299 MTIME= some date
(CLEARING)

when it all went by.

Needless to say, this was not pleasant to watch my work files (recoverable!)
vapourise.
