Because windows has the same behavior in this manner like unix. The port
number 0 is routed to the bind call, which  indicates the os to use a
random free socket port.

I don't think that this is a good idea, because by default tcp requires
a host *and* a port parameter and an omitted port attribute currently
indicates an error, which should no be changed in my opinion. Instead
setting port=0 indicates that the user knows what he are doing.
