Comment:

 There's patches in my `bug25127`
 [https://gitweb.torproject.org/user/isis/tor.git/log/?h=bug25127 branch].
 I'm not sure if I like what I came up with though. It might be better to
 make a macro to add the null bytes, similar to the one catalyst linked to,
 but probably without the `as *const ::std::os::raw::c_char` part.
 Opinions?
