Well, if you insist on having it again:

Waiting for atomic value to be zero:

        while (atomic_read(&x))
                continue;

and this I would say is buggy code all the way.

Not from a pure C level semantics, but from a "busy waiting is buggy"
semantics level and a "I'm inventing my own locking" semantics level.
