This article needs to be completely rewritten for the following reasons:

1) It confuses the problem of reading stale data with the problem of concurrent access. For example, it suggests that mutual exclusion is an alternative to using 'volatile'.

2) It fails to mention the two things that 'volatile' is actually both necessary and sufficient for, code that might be interrupted by a signal and code that uses 'longjmp'.

3) It talks about behavior that might happen to be true on some particular implementation as if it was guaranteed behavior.

No solution short of rewriting will address these problems, IMO.
