    I'd almost say DEBUG_PAGEALLOC; which could also disable lazy unmapping
    in order to catch use-after free better. Or just a different option

    DEBUG_VM has, so far, been kept to relatively cheap tests that are not
    much pain to turn on, and shouldn't result in much behavioural change
    of algorithms/data structures AFAIKS. Which can be a good thing.
