      There are a couple of places doing something like the following:

                      bool res = yield( suggestYieldMicros() , rec );
                _yieldSometimesTracker.resetLastTime();
                return res;

      If res if false, the 'this' pointer will have been deleted so calling _yieldSometimesTracker.resetLastTime() causes a write to invalid memory. I believe the resulting memory corruption causes SERVER-6480.
