** `port-for-each' makes an additional guarantee.
From the docstring: @var{proc} is applied exactly once to every port
that exists in the system at the time @var{port-for-each} is invoked.
Changes to the port table while @var{port-for-each} is running have no
effect as far as @var{port-for-each} is concerned.
This guarantee is important to make (ice-9 popen) work reliable.

Convert a printable string network address into an integer. Note
