In the early days of the regression suite, we used the 2001 port, but
have since moved everything to createServerSocket(0) which returns the
first available socket. There are still a number of old tests
which still use 2001, we should eliminate them.

Straightforward back port of the existing code.

The impact can be great, because the port can be unavailable due
to a previous run that stalled or another process inadvertantly using
the port. This has happened enough that we need to change this.
