I'd need to construct a more synthetic test to exercise this; it requires us to have fetched a memory region for a region that we get handed back by debugserver's memory-allocation packet.  e.g. a big block of "unmapped memory", then we allocate a page in the middle, and now that unmapped memory region info is inaccurate.
