You changed my code, so it works now? If not, just try. I have no idea, why it is not working at me, really. Please help.
All right. wait is not responsible for actualy making the request. How do I know?
Usually by reading the documentation, or by Devel::Trace (very verbose), but since this is LWP, LWP::Debug. Here's a little snip 
C:\>perl -MLWP::Debug=+ foobar.pl
LWP::UserAgent::new: ()
LWP::Parallel::UserAgent::in_order: (0)

***********snip**********

LWP::Parallel::UserAgent::register: (http://2ge.mine.nu/headers.php, [
+undef], [undef], [undef])
LWP::Parallel::UserAgent::wait:

        Pending Server: 1 [ 2ge.mine.nu:80, 10 ]

LWP::Parallel::UserAgent::_connect: (LWP::Parallel::UserAgent::Entry=H
+ASH(0x1cbb174) [http://2ge.mine.nu/headers.php] )

+6c)) [GET http://2ge.mine.nu/headers.php]

LWP::Parallel::UserAgent::_check_bandwith: (LWP::Parallel::UserAgent::

***********snip**********

LWP::Parallel::UserAgent::_perform_write: Writing to Sockets
LWP::Parallel::Protocol::http::write_request: write_request (HTTP::Req
+uest=HASH(0x1cac16c), IO::Socket::INET=GLOB(0x1d3e62c), /headers.php,

LWP::Parallel::Protocol::http::write_request: GET /headers.php HTTP/1.
+0
Host: 2ge.mine.nu
User-Agent: My agent 10

Now since most of these aren't documented, the time comes to source dive. I start by examining LWP::Parallel::Protocol::http::write_request (since it is responsible for making the request as evident by the trace), and I see 
sub write_request {
  my ($self, $request, $socket, $fullpath, $arg, $timeout, $proxy) = @
+_;
***********snip**********
  my $h = $request->headers->clone;
***********snip**********

[download]
but its not where the headers are set (agent isn't mentioned).

So now I look earlier in the trace, and this time I notice LWP::Parallel::UserAgent::init_request, so I examine it 

***********snip**********
    my ($agent, $from, $timeout, $cookie_jar,
        $use_eval, $parse_head, $max_size, $nonblock) =
      @{$self}{qw(agent from timeout cookie_jar
                  use_eval parse_head max_size nonblock)};

    # Set User-Agent and From headers if they are defined
    $request->init_header('User-Agent' => $agent) if $agent;

***********snip**********

[download]
and would you look at that I've found where the headers (in particular User-Agent) are initialized. See how that works?

Do you now know what you have to do?
