Rather than figuring out how fork and friends work you might want to do
something like the following (not tested):

    my $xml = "";
    my $ua= LWP::UserAgent->new;
    my $request = HTTP::Request->new('GET',
    'http://www.slashdot.org/slashdot.rdf');
    my $response = $ua->request($request, sub {
            my($data, $response, $protocol) = @_;
    
        # do something to data
            $xml .= $data;
    
            Gtk->main_iteration while Gtk->events_pending;
    }, 4096);
    
    here $xml should hold the file...
