I would expect that the test never fails, if one is not modifying
anything related to genalloc.

But if an error slips in during development of genalloc or anything
related (like the functions used to scan the bitmaps), I think it's
better to pull the handbrake immediately, because failure in tracking
correctly the memory allocation is likely to cause corruption and every
sort of mysterious weird errors.
