No - yes.

I think this is what happens today - 2 processes listen to the same socket.

There can only be one, so the second one fails, right.


Almost.
Now: the second process trying to call listen() on a (different) socket that is bound to the (same) address fails.

My question: does it harm for the same process to call listen() on the same socket twice.

Cheers,
