Comment (by andrea):

 Begin code review:

  * fff77d89d781dbb219c426b86055c31d3984ddd7 looks good to me
  * 1d4d991a67c03f47e26036b93842f1508c3cf660 looks fine
  * 32e27ae64bc796b64bd864765ce42bdc27c60281 lools okay

 Okay, I think this is ready to go if you feel confident in it.  Be sure to
 cherrypick 1a8299df65461ddde7034ff18ad2dfdbb6bf25ac before merging.
