:: NetworkRunParams
-> Maybe HostName
-> PortNumber
-> TimeoutServer ()
-> IO (IO ())

Returns an IO action that will run a TCP server conforming to the run parameters. Will bind to localhost / loopback device only if no host name is specified. Will throw an exception when TCP server startup fails - the caller is responsible for appropriately reacting to that.
