It remains incredulous to me that webkit persists in the belief that it makes sense to users (or developers) that there is an inherent race condition in the way things are currently implemented with shift+refresh and resource re-validation.

If I ask for 4 scripts to dynamically load, and (for any of a variety of reaons) 3 of the 4 are requested "during page load" (aka, before DOM-ready or before window.onload -- not sure which that means?), and the 4th ends up being requested just a fraction of a second "after"... then when i shift+reload the page, only 3 of the 4 scripts are re-validated. That inconsistency is inexcusable.

That situation is extremely common in my development experience, and it's inherently a race condition of which resources get requested soon enough to qualify as "during page load". It's crazy to me that we can't figure out a way to address this. Not seeing the reality of how that negatively affects users/developers shows that the people making decisions here are out of touch with real web development.

No matter what type of explanation you make for why resources loaded "after page load" don't get re-validated (I've read the explanations dozens of times and it's still confusing to me), there's no way around the fact that this optimization strategy creates the side effect of confusing race condition behavior for pages which use dynamic resource loading techniques during page load. In every sense of the phrase, that type of racey behavior violates "principle of least surprise".
