We don't use the worker pool yet, however, there are tests. Yay. The next step is to use the worker pool for parallel sweeping. I've also started to move the platform related files into a sub directory. The goal is to eventually build all the platform stuff as a separate library which is used by d8 and cctest (and other embedders that wish to use the default implementation) but not by chromium.
