If process 1 is using a port then process 2 should try the next port in the
range until it finds an available one (or runs out of ports). There are 1000
ports to choose from, so it should be able to find a free one.

The job won't run without my patch due to the restrictive firewall on the
individual machines. I ran tests with only a single process per node and
encountered the same problem, so the problem doesn't appear to be due to
processes arguing over ports.
