1) Don't do it
2) If you made it to this point, KDE doesn't support it right now since we 
would have to link against qt-mt for that. (As you already found out)
3) For KDE 3.0 I guess it would make sense to use qt-mt by default not 
withstanding point 1). For that it would be helpfull if people started to 
share their experiences with multi-threading & KDE so that we know what to 
watch out for.

This recent slashdot article about multithreading seems to be very nice.

Rik also wrote some interesting stuff about threading. I'm sure he will react 
to your msg as well :-)

Cheers,
Waldo
