I'm working on some LMB cleanups now, among others trying to take into
account what I think are Yinghai requirements. Give me a few days.

For the specific problem above, my idea is to have the low level alloc
function be able to take both low and high limits, so that x86 can
figure out what's best for a given allocation.

Cheers,
