This is not correct.  I cannot reproduce this on a machine where
deduplication has been disabled.

Line 62 is (port-position wrapper).  =E2=80=9Cseek=E2=80=9D takes an intege=
r as the
offset and the range it reports is that of the minimum and maximum
values of a 32 bit integer.

So=E2=80=A6 does this mean that we need some other way of counting written =
bytes
to get rid of =E2=80=9Ccounting-wrapper-port=E2=80=9D?

On berlin.guixsd.org I may have to temporarily disable deduplication.
