Currently browser and renderer execute V8-related code (including GC) in the main thread. So a lot of synchronization is actually unused and only makes us slower. I don't do the full cleanup (but would do on request) to make it easier to rollback this synchronization infrastructure if need be. On the other side that's exactly what version control should do.
