Add a multiprocess mode to the object replicator. Setting the replicator_workers setting to a positive value N will result in the replicator using up to N worker processes to perform replication tasks. At most one worker per disk will be spawned. Worker process logs will have a bit of information prepended so operators can tell which messages came from which worker. The prefix is “[worker M/N pid=P] “, where M is the worker’s index, N is the total number of workers, and P is the process ID. Every message from the replicator’s logger will have the prefix
