Can this file be in content/renderer? I think if we need it shared between
different child process types, then it goes in content/child. content/common is
stuff stared between browser and child processes, which I don't think this is.

Done. Hmmm... yes. As of right now the only user will be the renderer. If we
need to change that later, we can.

Long lines (in this case I'd normally just wrap the arg on the next line.

[bungeman-chromium, 2014/03/13 22:33:31]

Done.

I'm not sure what this is for.

[bungeman-chromium, 2014/03/13 22:33:31]

Done. Left-over from the initial implementation. Skia has a debug ref-counting
setup where this is used, but this isn't in Skia, so doesn't need it. Removed.
