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.
