You can also define a \stopXXX command where you can load the buffer 
content and do something with it once you reach the end of the buffer, 
this is a feature of the environment itself.

%%%% begin example
\definebuffer[Jim]

\protected\def\stopJim
   {\startframedtext
    \getJim
    \stopframedtext}

% alternative way to define \stopJim
%\starttexdefinition protected stopJim
%  \startframedtext
%  \getJim
%  \stopframedtext
%\stoptexdefinition

\starttext

\startJim
This is Jim’s buffer!
\stopJim

\stoptext
%%%% end example
