Chrome uses TODO(id). WebKit uses FIXME.

indent 4.
verify implies it should be sandboxed. Maybe test_pepper_broker.txt.

While it makes the code harder to read, these should all be 2 lines.

This part is OS-specific. You might be able to use
http://codesearch.google.com/#OAMlx_jo-ck/src/base/sync_socket.h&type=cs to
avoid this.
