It isn't like they would dump it all at once, that isn't feasible. Immediately picked up by who though? the only country with as much holdings is Japan and they certainly are in no position to be buying volume. Sure, I'm not doubting the treasuries wouldn't be purchased but the potentially of flooding the market with U.S debt would certainly impede on new treasuries the U.S inevitably sells later. Just a thought, I'm certainly no expert (clearly)

If need be Fed can pickup treasuries at discount. China selling at discount though is China losing 100B+ while US buys back its debt cents on a dollar, sounds like a good deal for the US.
