It turns out that the extra whitespace before and after the section headers
in the body appears when I put \startcolumns[n=2] before the body text and
\stopcolumns after it.  Here's the MWE, just slightly modified from your
example:

%%%% begin example
\setuphead
   [chapter,section,subsection,subsubsection]
   [before={\blank[nowhite]},
    after={\blank[nowhite]}]

\setupwhitespace
   [medium]

%\showgrid

\starttext

\startcolumns[n=2]

\completecontent

\chapter{Chapter}

\samplefile{knuth}

\section{Section}

\samplefile{weisman}

\subsection{Subsection}

\samplefile{weisman}

\subsubsection{Subsubsection}

\samplefile{weisman}

\stopcolumns

\stoptext
%%%% end example
