      Description

      During a replica set reconfig, each node independently increments and installs the new config. While this is happening, it is possible for a node to attempt to run an updatePosition command on a sync source node with a different config version than its own. Currently, the code tries again immediately until the config versions between the two nodes becomes the same and the updatePosition command finally succeeds; this can result in heavy network traffic.
      One stopgap solution to this problem is to put in a sleep between retries.
