I doubt this helps except you meant processes rather than threads.

Unfortunately, konqueror uses threads, at least in 3.5. When the kpdf 
embedded viewer crashes, as it does, you lose the entire browser as well.

I believe you are confusing netscape plugins and kpart components that get loaded. In the case
of kpdf, yes, the kpdf part operates as an in process component, but in the case of an
netscape plugin, they get loaded and run in the nspluginview process and get displayed via
dcop into the browser window.

yokem_55 is correct, netscape plugins are ran via nspluginviewer (which 
allowed a neat trick of using the 32bit version on a 64bit system to 
easily run 32bit plugins in a 64bit browser).

Unfortunately, it's still possible (or was in the past) for Flash to 
misbehave very badly and freeze the Konqueror process or even crash it 
(I'm not sure I've seen it crash because of Flash since around when Flash9 
was released, I'm not sure if thats thanks to Konqueror being improved or 
Flash or both though). In the case where Flash (or any other plugin) 
freezes Konqueror, I've always been able to unfreeze Konqueror by simply 
killing the nspluginviewer process.

IIRC, Konqueror was designed that way to prevent the plugin's main loop 
from conflicting with Konqueror's and causing all sorts of nasty 
situations.
