g_is_main_thread only changes the behaviour of open_resource(), so either
mention that, or omit the comment, otherwise it's rather cryptic.

Done.

Nit: Why not just "return nacl::nonsfi::...;"?

[hidehiko, 2014/02/19 13:05:02]

Oops, I forgot to fix the style... Done.
(I printf-debugged the returned pointer...)
