Eventually, if we might want these parameters as rdma connection setup parameters. For now, its useful to be able to set them without reloading. Also, it is safe to change them at any time. All of these are read once and utilized at connection setup. So changing them is safe in that existing connections aren't affected, and only subsequent connections will utilize the new values. Sorry for the terse changelog... Steve.
