Thank you! I won't have an opportunity to watch the boys this week, so I'll check how much this helped next week.

There are still many media related crashes on the bots; hard to tell if these are the same or separate ones :( https://build.webkit.org/results/Apple%20Yosemite%20Release%20WK2%20(Tests)/r176591%20(983)/media/video-load-networkState-crash-log.txt https://build.webkit.org/results/Apple%20Yosemite%20Release%20WK2%20(Tests)/r176596%20(988)/media/video-empty-source-crash-log.txt https://build.webkit.org/results/Apple%20Yosemite%20Release%20WK2%20(Tests)/r176598%20(989)/media/track/track-in-band-duplicate-tracks-when-source-changes-crash-log.txt

It doesn't look like overall crashiness reduced, and having a timeout makes it harder to deal with. So, rolled out. Probably not worth tracking this as a Bugzilla bug, as the bug existed to try this specific approach to fixing the problem.
