nit: in case you didn't notice, you can use a shorter name
BlobChannelMojoRequest

Done.

Does this ever get deleted? Does it happen automatically when the binding is

If so; could you add a comment about this here, so it doesn't look like it's

[Kevin M, 2016/04/06 00:01:44]

Yes, its StrongBinding |binding_| controls the lifetime. Added comment.
