That's why we need more information regarding this strange slowdown.

I have access to almost the same machine (a 450 MHz P II)...
With KDE3.1 (Suse8.0 packages) top shows 1.9 % constant CPU utilization
for kded. strace confirms that this is indeed a row of stats every 0,5 
seconds. But my estimation of 40 dirs was wrong: There are at least >150 dirs 
watched (Standard KDE desktop dirs + a LOT of additional Suse dirs) :-(

OK. This is bad. But:
kwrite startup time is roughly 3 s, regardless of whether kded is running or 
not (you can kill it temporarily without much harm. Run "kdeinit" to have it 
back).
So I can't reproduce this problem.

BTW: My bash-loop was misleading. Writing as fast as you can will always give 
high system load. Aside from that, KDirLister has a 0,5 seconds delay (and 
thus, merging), hardcoded. Neverless, the realtime signals are produced...
