In WebCore there are a lot of instances of one header including another when it could forward declare instead. Using forward declares more aggressively can improve compile time, especially incremental.

The Visual Studio IncludeManager plugin generated this list containing the number of includers/includees for each file as well as the number of tokens and an estimation of their build impact.

I've simply been going through some of the more expensive headers and looking at each include line to see if it can be forward declared instead. I encourage others to pick a few, it is a surprisingly zen task.
