This was introduced by  302350.  It broke the return value of 
callout_{stop,drain}. returning 1 even if the callout system did not hold a 
reference. That in turn broke the following code in lltable_free:

LIST_FOREACH_SAFE(lle, , lle_chain, next) {
if (callout_stop(>lle_timer) > 0)
LLE_REMREF(lle);
llentry_free(lle);
}

Thanks for that.  I've added myself to the cc list, and a comment about 
having 2 vmcore's.
