I haven't tested these old 10.6 bots, but I believe we're about to retire them
anyway (they've been red for a year or so and no one have bothered working on
suppressing/fixing them).

Yeah this won't work on the 10.6 bots. I would suggest deleting the 10.6 bots
and deleting these test cases at the same time, just so no one thinks something
works when it doesn't.

I'm removing these bots in https://codereview.chromium.org/573693002/
