At the risk of asking a potentially silly question, would it be

result in poor system behavior before enough memory is validated?
Perhaps we should block instead of failing allocations if we want more
memory than is currently validated?

It can't be _that_ big of a problem since we already have
DEFERRED_STRUCT_PAGE_INIT causing the same kind of issue.
