IDK what the TODO above this line is about, but if this dlopen falls under it,
then probably it should move above the TODO, and if it does not, it probably
warrants a newline between the TODO above and this dlopen, and maybe even a
clarification of the TODO that it refers to the libs _preceding_ it.

David's CL https://codereview.chromium.org/179983006/ removes these preload
libraries altogether. I see it is merged just a few hours ago.
Will rebase and upload another patchset.
