bgwriter is now a much less important process, responsible for page cleaning duties only. checkpointer is now responsible for checkpoints and so has a key role in shutdown. Later patches will correct doc references to the now old idea that bgwriter performs checkpoints. Has beneficial effect on performance at high write rates, but mainly refactoring to more easily allow changes for power reduction by simplifying previously tortuous code around required to allow page cleaning and checkpointing to time slice in the same process. Patch by me, Review by Dickson Guedes
