Add more chattiness in server shutdown.
Early returns from the buildfarm show that there's a bit of a gap in thelogging I added in3971f64: the portion of CreateCheckPoint()after CheckPointGuts() can take a fair amount of time. Add a few morelog messages in that section of code. This too shall be reverted later.
