      Description

      The mongos server parameters defined here were meant to be linked only into mongos. They are also linked into mongod.

      To complicate things, each of the parameters is used in a "hot" area of mongod/mongos cross-linkage, such as async_requests_sender.cpp and sharding_initialization.cpp.

      We will need to assess the complications that arise from having these parameters caught in the mongod/mongos cross-link web, and whether setting the parameter on mongod causes odd behavior in a sharded cluster.
