Comment:

 OK this is now in **merge_ready**!

 Here are the updates:

 The final (squashed) branch is in
 https://github.com/torproject/tor/pull/624.
 The identical-but-unsquashed branch is in
 https://github.com/torproject/tor/pull/623 (as per mike's post above).
 Nick's last review comments from `PR#461` have been addressed and answered
 by referencing the commits in `PR#623`.

 This branch is ready to be reviewed & merged. It does not actually enable
 any machines atm, but let's see if we can fit something in for 040 after
 we merge this.
