I am not a TCP/IP specialist, but I would guess that the loop
could be written:

         for ( $waitpid=0
	      ($paddr = accept(Client,Server));
               $waitedpid = 0, close Client)
         {
             my($port,$iaddr) = sockaddr_in($paddr);

ie skip the $waitpid condition in the for(), and forget about the
if($waitpid) in the body of the loop.

In my opinion this should work fine.

I don't know, but it's may be related to signal handling changes.
