 # The core loading code in this directory is being transitioned into a separate
 # Mojo networking service. See http://crbug.com/598073. The first stage is to
 # decouple the code that will be moved from the rest of content. These rules
 # help ensure that we don't add more includes, and can progressively reduce the
 # code's dependencies.
 #
 # For each file, the first section shows includes that are allowed (i.e. because
 # they are for files that will be moving as well). The second section, separated
 # by a comment, lists files that we will have to decouple.

I'm not 100% sure on this, but hopefully it's not a problem.

@scottmg, can you take a look (per https://codereview.chromium.org/1914063003)? 
(jam@ appears to be OOO.)

[scottmg, 2016/06/02 00:14:33]

Yes, I think that's probably OK. Can you also move the instance on line 156 up
to the "OK" list?

Done.
