Doing it manually is how it's done in C. And the results are it is a 
massive failure. It's just impractical to write reliable, portable, 
inspectable, and maintainable multithreaded code in C. Even the experts 
can't get the trivial cases right, as there was a famous recent example 
in Dr. Dobb's (forgot the name of the article at the moment).
