Not sure i understand the question.  All of the other cpu's are stopped
while the system is in the debugger; and nothing is running except the 
debugger itself.   Thus even the stack of a "running" process is frozen
in time.   

Its useful to look at the stacks on other cpu's since they sometimes
deadlock against each other.
