/** @file server.h
This file contains includes commonly needed in the server files (mongod, mongos, test). It is *NOT* included in the C++ client; i.e.
this is a very good place for global-ish things that you don't need to be in the client lib.
Over time we should move more here, and more out of pch.h. And get rid of pch.h at some point.
