Writing a self-modifying x86 factorial program

Doesn't self-modifying code cause massive cache flushes and stalls on modern x86 archs?

Not even that modern. The self-modifying code in the article would be slow even on chips produced in the 1990s.

Any processor using pipelines suffers from self modifying code. The Intel 80486 was the first x86 chip to have a pipeline, and it was released in April 1989(!). Granted, it only had a 5 stage pipeline, so you'd only lose a few clocks each time, but modern x86 architectures have pipelines dozens of stages deep.
