Right, I should read docs first, next time ;)

That could be a problem, anyway. How can you be sure all the kipi's developer
will use qDebug instead of kdDebug?

I do believe kdDebug developers should be aware of the problem and provide
a thread safe solution, if the attached patches could be useful for them they could
use those ones, IMO.

Another possible way could be having a "stringstream" for any threads in a map by thread id
and sinchronize the access to the output every time an eot/eol/eof is coming 
(overload of overflow method). But I didn't think a lot to a real solution though...
