Tab switch spinners can occur anytime that the content process hasn't given us a layer tree in enough time to composite them in response to a user switching tabs. I want to know when, in a tabs lifetime, those spinners are likely to occur. I'm going to break a tabs lifetime down into three discrete chunks: 1) Tab is new* and has never been seen 2) Tab is not new* and has never been seen 3) Tab is one we've seen before, and we're switching back to it. My hypothesis is that we tend to show a lot of spinners in case (1). If so, I suspect there are ways we can address those. * newness is the fuzzy part of this. I need to settle on a solid definition of newness - perhaps as a measure of time since the tab was created.
