I have an idea what's need to be done to improve this and some others
sha256 formats.
The problem is that I will not have time for that in the next 3 weeks
because of exams.
I planned for this weekend some other minor/trivial changes that I
think we need before jumbo release, but that's all what I can do at
the moment.
I added this task next to gpu pbkdf2-sha512 to my todo list.
