Re: Output from sudo kill -QUIT pid

That's correct. SpawnOfWotaskd.sh is the script used to launch  
application instances.

Attaching via gdb likely won't help you - "bt" (or "t a a bt") will  
only give you the native stacks, which are probably not helpful. Even  
"call (void)pss()" (which generates the same output as "kill -QUIT")  
dumps it's output to the same place "kill -QUIT" would have (in this  
case, yes, it defaults to /dev/null - my bad).

Jake liked his women the way he liked his kiwi fruit; sweet yet tart,  
firm-fleshed yet yielding to the touch, and covered with short, brown,  
fuzzy hair.
