It would appear that this problem is still the case, as of the
following version:
$ context --version | sed -n 2p\;5p
mtx-context | ConTeXt Process Management 0.63
mtx-context | current version: 2016.09.24 12:40
In particular, Peter's example produces something like the following:
(I'm assuming these 90-character-plus-CRLF lines made it through the
Internet; if they did not make it, then someone's email-processing
software is non-conformant, so shame on him!)

However, a person whose thoughts are governed by reasonable logic might
instead expect the result to look more like this:

The ConTeXt facilities in question are [mostly] defined here:
"$TEXROOT"/texmf-context/tex/context/base/mkiv/page-mul.mkiv
After a not-so-cursory review, it seems to me that the problem is a
result of [probably erroneous] references [in various calculations]
to the `offset' parameter, which is presumably a vestigial growth
inherited from `\setupframed'.
Fortunately, meddling by this `offset' parameter can be explicitly
nullfied via including `offset=0pt' in the setup parameters for the
`\startcolumns' command; that is, in order to get the results that
Peter expected, modify Peter's example to be this:
--8<---cut here---start->8---
\starttext
\startcolumns[offset=0pt,distance=0pt]
\input tufte
\stopcolumns
\stoptext
--8<---cut here---end--->8---
If you now include `rule=on', then you get:

If you now replace `distance=0pt' with `distance=2ex', then you get the
following (I chose `2ex', so as to be able to represent the results more
accurately in plain text):
