=> 32k available but 1/2 collision probability after ~180 ports.
More seriously I really prefer the "more robust" option as I
run tests on an other purpose machine. BTW a feature which
is very useful in some cases should come for free (i.e. just
check it works) with random is to be able to run simultaneously;
the same test on different builds.
