Description Mark Rowe (bdash) 2014-01-14 03:07:13 PST

* STEPS TO REPRODUCE
1. Run Safari under the Sudden Termination instrument in Instruments.
2. Wait for a minute or two until everything has settled down.
3. Load <http://imgur.com/YeY7H76> in a new tab.
4. Close the new tab from 3.
5. Repeat 3-4 a few more times.

* RESULTS
The disable count grows each time.

* NOTES
It looks as though the web process makes the relevant ChromeClient call prior to exiting, but the UI process never receives it.
