Look's like node 7 is done. The "totals" are waiting for it to answer, 
so it never shows either. After the above scenario, try running "grep ^7 
john.log"

That version you've got is not too clever with few rules. For example, 
with 7 rules against 8 cores the last node won't get any. Or with 14 
rules, node 0-5 will have two rules each, while node 6 and 7 only gets 
one each. I'm regression testing better ways of handling this.
