That pretty much sums it up. Something with SO_REUSEADDR or SO_REUSEPORT
might work in the socket API (and thus somhow in the netconn API), but
I'm not sure. That's just not what TCP is used like nowadays.
The TCP standard even handles "simultaneous open" but this is another
thing we don't support as noone seems to care...
