I may be mis-understanding something here, but normal way would be to install handler for $SIG{CHLD} in the parent, like: 
#kill zombie children
$SIG{CHLD} = 'reaper';

while (1)
{
   server code to accept new clients and fork()...
}

sub reaper
{
   my ($kidpid);

   while (($kidpid = waitpid(-1,WNOHANG))>0 )
   {
      print "Reaped $kidpid\n";
   }
   close $client;
}

Update: I think: use POSIX qw(sys_wait_h); is needed too.
