Comment 37 for bug 693524

Alberto: By way of explanation, many of these bugs were stalled for a long time due to circumstances outside our control: with the old Xen/hardy-based virtual builder infrastructure, we weren't able to fix many of these in any kind of sensible way. Now that the new OpenStack/trusty-based virtual builder infrastructure has been rolled out (which happened last Monday), we've finally been able to make progress again on some of these older buildd bugs.
