I would like to clarify implementation details a bit more from this 
programming attempt. Can it be that the referenced text buffer is 
written in a thread-unsafe way here?
How do think about to apply improved techniques and software ingredients 
like locks for memory consistency?
(Andrew Potter and Gavin Lambert suggested also an alternative program 
structure. -
