      1) Manually start a mongos/d with a named pidfile
      2) Try to manually start another mongos/d using the same named pidfile
      3) The second instance inserts its own pid into the pidfile, and if it's asked to use the same port as the first mongos/d, it dies, leaving a stale pidfile and a dangling server.

      When mongod/s starts up, if it is told to use a pidfile, it will overwrite that pidfile, even if that pidfile belongs to another mongod/s process that is currently running.

      It should check to see if the pid in the pidfile is active and refuse to start if it is given a pidfile that corresponds to a running process.
