find a free port?
I think that's basically it.
If the range is large, we can bind to an arbitrary port, then close and
re-bind if you don't like the OS choice.
If the range is small, we can choose a random port, and bind specifically
to it, and then choose another port if it fails.
Sounds like a denial of service risk to me, either way.
