Okay, the problems in question seem to be Mac-specific.  If I run,

    oscdump 7570 224.0.1.3

in multiple terminals on Linux it works fine, but on OS X, I get,

    cannot find free port

The error goes away if I re-add the SO_REUSEPORT option.

Not sure exactly under what conditions it's appropriate then, I'll
have to do some research.
