The lack of -e means it's big endian, which is not a big issue. So here
most of memory is free, some pages have just one pin, and only
relatively few have more. The vmstats also doesn't show anything bad, so
we'll have to wait if something appears within the week, or after you
try 4.9 again. Thanks.
