they left me with reason to find the misplaced packet of curare-tipped darts ... leaving Safari (necessarily running to hit their site) sufficiently inaccessible that, trying to kill its throbbing corpus--crashed the sucker instantly.

Not an easy recovery.. as with 'Doze of old: the Third reboot was the charm (by the second, was blaming-self for misplacing the bloody darts.) El Capitan did/does seem a bit sprier for its absence/Bonus. And Activity Monitor kinda confirms ..doing less work now. Nice.
