> This change addresses two issues in plasma notification code:
> # Currently plasma store uses recv_fd to receive the notification fd from
> client. As mentioned in comments from the code, this could cause plasma store
> to hang if client doesn't call send_fd. This particular change puts the
> notification fd in SubscriptionRequest to solve the problem.
> # When a client subscribes to plasma store, the store pushes notifications
> of existing objects to ALL subscribers - while in this case it just needs to
> push to the new subscriber. This change adds a new interface to push to a
> particular client.
