Web Inspector: Flame Chart. Developers will have more clue if two different profiles will have same colors for same functions.

[Ilya Tikhonovsky]

scenario:

developer made CPUProfile on a page.
developer fixed the problem
developer made another CPUProfile 
developer has to see the difference
but he might be confused by the different colors associated with the same function in the different profiles.

You can't declare properties on alien objects, just make it static!

Why do you need this variable?
