One issue I've found with Net::Server even once it is patched, is that if 
the hostname is "localhost", it comes back resolved twice as if 
you have both IPv4 and IPv6 enabled for localhost.  It looks like it would 
do the same thing for any hostname that's so enabled.

This causes startup problems for applications that use Net::Server to bind 
to the IP address, because they try to bind twice to [port], and 
then fail to start since it is already bound.
