FWIW, I think this big is at worst just a memory leak. Once an mm has any LDT mapped, mapping a second one can't fail because the entire LDT area is under 512 pages, meaning that nothing needs to be allocated, so there's no opportunity for failure.

So it's an embarrassing bug, but not catastrophic.
