It's looking to me like the Android debug slowdown is a little excessive, so at least for now, I'd like to disable the additional checks on that platform and configuration only.

this is valid

I think that makes sense. There shouldn't be much Android-specific code that interacts with gray marking.

oops, I never posted the patch for review.

sfink - Thanks very much for your efforts here. +1 for the strategy of checking less on Android...but are you sure it is working? I was expecting a dramatic savings, but the Android Debug job times look about the same before/after your push on inbound, and some of the timeouts that started with the gray marking seem to be persisting (there have only been a few pushes since yours, so it's early and hard to say, but a few of the timeout failures have happened already). Maybe the ifdef is wrong somehow? Maybe most of the time for gray marking is going somewhere else??

There's also the "run the GC over and over again!" checks that might be taking lots of time.

Needs more work.

:sfink, sorry this fix didn't do the trick :( Do you have another fix in the works that will land this week? We are a couple weeks into some top intermittents and I would like to temporarily disable on Friday if we don't have something close to landing by then.

Moar Android test disabling.

Yeah, I'm throwing in the towel and disabling bug 1335751 entirely on Android.

First few Android test results on inbound are looking good now. Thanks Steve.
