Are there any working tools available for debugging a threaded  
application in 5.3/5.4?  Ktrace works fine but doesn't identify the  
threads so its almost impossible to figure out whats going on in a  
complex threaded application.  Strace doesn't show threads either.   
Pstack causes all sorts of problems with the running application -  
usually creating multiple copies of it none of which work anymore.
