Then you need to provide a slightly more complex server instance, that is a multiplexed reader. This will not wait for individual actions to complete and will allow you to close incoming reads if the sleep script is currently running yet respond to any read if sleep has finished? 
while (1) {
   ($read, $write, $err) = IO::Select->select($sockin, $sockout, $sock
+err, 1);

   for $sock (@$read) {
       $sock->recv($data, 1024 * 64, 0);
       next if $! == EAGAIN() || $! == EWOULDBLOCK();
       next if (-e 'server.pid');
       system ('./sleep.pl');
   }
}
