A page may have many frames with distinct render trees.  I'm not sure you mean to name it this way.

is totalArenaSize accurate for your needs?  Does it sum up all the object sizes?  Does it include free space?  Do you want it to?

Do you have a suggestion? Not sure what's wrong with this name. This is the sum of the render tree sizes of all the frames in the page. I was just reusing the name from the WebKit2 code.

I have a followup patch that also gathers the total allocated bytes (i.e. includes the free space). I think, for the purposes of histograms, we want both numbers.
