As far as I can tell, that Abercrombie sentence is not a comma splice. She, explicitly or implicitly, is always the subject.
Okay, there's one bit where she isn't the subject - - as the subject is the bit I've put in bold, but the verb here - washing over - is not a main verb and so the quote isn't something that would stand on it's own. In fact, one doesn't have to know much grammar to see that it isn't a complete sentence in itself.
I agree. Even the part you've quoted is a participial phrase isn't it, acting as an adjective? So even it is not a comma splice. I think it's a well formed sentence that is absolutely loaded with participial phrases. Of course, they're all present participles, meaning that all this description has to be happening at the same time as the action in the modified clause, but that's a different matter.
There is one strange construction, the phrase "..., could not breathe, ..." As constructed, it would have an implied subject of she, but that would then form a comma splice. It's the only bit that sounds odd to me. I'd have probably went with "unable to breathe."
TDZ, I don't think it's a run on either. That would require two joined sentences with the conjunction but without the comma (sort of the reverse of a comma splice). That is, if a run on, by your reckoning, is the same as a fused sentence, which is how I was taught.
Anyway, here's a good use of a comma splice from Hemingway's short story, The Battler:
The man looked at Nick and smiled. In the firelight Nick saw that his face was misshapen. His nose was sunken, his eyes were slits, he had queer-shaped lips. Nick did not perceive all of this at once, he only saw the man's face was queerly formed and mutilated. It was like putty in color. Dead looking in the firelight.
Here the comma splice serves the rhythm of the description. Awesome. (Hemingway is known for nonstandard comma use, but you see way more run ons than comma splices.)
Here's a great long list of comma splices, many of them beautiful bits of writing, done by all sorts of authors:
