Obviously this is the perfect candidate for cmocka. A small
independent piece of code that needs testing. Yes, I've seen your talk
in Göttingen about cmocka, but still it would be great to get your
support how to use cmocka in this case, now that I have a piece of
code that is contained enough and that needs this. Can you walk us
through adding cmocka here to make pthread_create fail
deterministically?
