Starting two servers on the same port should fail

see this thread:

I start up a ftp server in my unit tests. But I want to make sure
there is only one instance running on a port, starting a second server
on the same port should fail (throw an exception).

Right now the second server starts up without errors but making a
connection to the port used gives me the first server...

Windows has a weird (or wrong)
treatment of SO_REUSEADDR. You can read more about it here:

This has been discussed here before, but with no good resolution. One
possibility is that we could make our use of SO_REUSEADDR
configurable.
