I'd say it's safe to assume he meant that she'd have to be destroyed completely all in an instant with no part of her still existing for even a nanosecond later.
You guys need to read the chapter a little more carefully.
"Most of the time injuries will heal faster than they can be inflicted." Flechette looked at him and raised her eyebrows. "You're not going to see wounds visibly closing. If you prick your finger it will have healed by the time the needle is out. Actually, sort of before that, but the mechanics get a bit complicated."
Among other things there's what sounds like an instant time reversal effect to make any damage never have happened and...
"Not really." He said flippantly. "The complete destruction of your entire body on a fundamental level across multiple dimensions, inclusive of the surrounding fabric of space-time might do it, but that's not really something you can 'look out' for."
It's not enough to destroy the persons entire body across multiple dimensions, you need to basically vacuum collapse the local universe too.
I assume if you did drop a sting empowered anvil big enough to totally erase Flechette's body from existence she'd have been standing nearby (and would always have been), with the anvil closely missing.
