Awesome!

The biggest mental block I had was getting the state out of libdbus
about the state of connections to Upstart, state of messages, etc.

Restarting Upstart shouldn't drop in-progress commands.

Bug description:
Upstart needs to be able to transfer its state across a re-exec.  This can then be used for safely restarting (e.g. after a libc or upstart upgrade), and for changing of root device (e.g. initramfs to full system)
