Mathieu, you are correct, upstart makes it hard to know what's hanging since it's happening in parrallel in a non deterministic fashion, and it's not like I can run ps at that time.
I originally filed this against upstart, because quite franlky upstart does not make it easy to see what the problem is. I however think the problem is with the network-manager init script. I think when I had auto eth0 iface eth0 inet dhcp It would sometimes bring try to bring up eth0 when it wasn't plugged in, and hang.
