I assume that the overhead only occurs for small files...


ZnClient new 
        signalProgress: true;
        systemPolicy;
        beOneShot;
        url: 'http://smalltalkhub.com/mc/estebanlm/Voyage/main?format=raw';
        get.

with progress 2.5secs without, 57ms.. :/ well might be that the server
responds with an incomplete header or so...
