If I recall it wasn't that I didn't understand the concepts but rather difficulty in debugging. At the time I was ignorant and ill experienced of proper tooling. Today when dealing with C I would probably not even bother with using threads and might just use multiple processes. I agree on the reimplementing POSIX threading and despite my rough experience pthreads was worthwhile learning about.
