I wonder whether the unified sources builds would still allow us to
keep using compiler caches like ccache.

Second question/caveat is, wouldn't the bundle build penalize too much
incremental builds? If your data is correct we would get a <20% build
time increment for a single change in a cpp file which is I think the
most common scenario for a WebKit developer.

Don't get me wrong, I'm really excited about this change, just wanted
to make sure that it does not penalize too much other scenarios.
