+Set the number of query and write worker processes for parallelism.
+
+C<QUERY_WORKERS> defaults to the number of CPUs available, but 4 per
+remote (HTTP/HTTPS) host.
+
+C<WRITE_WORKERS> defaults to 75% of the number of CPUs available for
+Maildir and mbox* destinations, but 4 per IMAP/IMAPS host.
+
+Omitting C<QUERY_WORKERS> but leaving the comma (C<,>) allows
+one to only set C<WRITE_WORKERS>
