Talal, here is a barbarous workaround using \thinrule:

======================
\setuppapersize[A6]
\starttext \showframe

\setupthinrules[color=white]
\setupwhitespace[big]

\section{Incorrect}
\startlinenumbering
\startalignment[r2l]
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Pellentesque  
molestie dictum quam non congue. Integer ut dolor vel mi vestibulum  
molestie vel et nulla.\thinrule

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Pellentesque  
molestie dictum quam non congue. Integer ut dolor vel mi vestibulum  
molestie vel et nulla.
\stopalignment
\stoplinenumbering

\section{Correct}
\startalignment[r2l]
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Pellentesque  
molestie dictum quam non congue. Integer ut dolor vel mi vestibulum  
molestie vel et nulla.
\stopalignment

\stoptext
======================

This effectively hides the problem. Unfortunately it is apparently not  
straightforward to invoke the \thinrule automatically at the end of every  
paragraph [see the other thread with Alan].

Best wishes
