see memory snapshot in attached trace

I was intentionally trying to create the situation of a super long email in gmail by repeating (select all, copy, paste). Then fast flinging the webview containing this super long message caused the app to be killed due to low memory while it's foreground.

Looking at the trace, can see that cc tile memory has a reported 875mb. However this does not show up in the resident set or from anything in dumpsys meminfo, which is super weird. This is GPU raster, so all the tiles should be GPU memory, so maybe it's just that GPU memory don't show up there, meh I'm using refs/heads/master@{#534378}, on a nexus 5 running M4B30Z.

Don't have time today to try other devices or do bisect..
