You can, of course, add a querier (or configure it, assuming an
attached switch supports it) and set the query interval and
robustness count as appropriate for that network.

Presumably the IPoIB multicast router should already be the querier..
How does this help handling joins to new groups?

        Because a querier can set the robustness value and
query interval to anything you want. In the original report,
he's not running a querier. The fact that it's a new group
doesn't matter -- these are per-interface.
