	Any daemon that wants to listen for connections needs its own port 
if the shared port daemon is not in use.  The shadow routinely listens for 
new connections, for example, when doing file transfer.  I'm not familiar 
with every possible use of listen sockets, so I can't be more specific. 
Remember that allocated ports frequently outnumber live connections and 
that in many cases, a TCP port number can't be reused immediately.
