I just did the merge and it's using a relatively untested new KPI so 
regressions aren't too surprising I'm afraid. #96 is more or less content free 
in terms of providing useful information. Getting a core + backtrace would be a 
lot more helpful. See the repo's wiki for details on improving your odds of 
getting a core.
