libthr broken

Hi

Does anybody really use libthr? It's broken for me, as long as I
remember. The real application which best shows off is KNode, just
jump into some big binaries group and start sniffing around.
Download some pictures as fast as you can click and watch in a row,
then stop some downloads and it'll die. But only if the threading
library is libthr. I believe this isn't KNode's fault as it was for
long time in KDE 2.x series.
