OK so after discussing this with Dan I decided to implement a queue for DNS prefetching control for the libsoup backend similar to what other ports have. It works pretty well (for example bug 80587 is fixed by that patch) but there are two important things missing:

1- proxy detection. Is there any reliable way to detect that we're under a proxy without depending on GNOME system settings and the like? I guess we can completely get rid of prefetching when behind a proxy.
2- soup_session_prepare_for_uri() does not have a callback. We need it to limit the maximum amount of simultaneous DNS requests we issue. We can add a signal to libsoup or deprecate it and add a new one with the usual _async() parameters. I think I'm more in favour of the latter.

Dan?
