What I mean, is a stack PROT_GROWSDOWN RLIM_INFINITY RLIMIT_STACK mapping is
defined to be a mapping from the top of that mapping down to the first mapping
of something else below it.  Whether it is the shadow memory or something else
doesn't matter.  There is just no overlap in that case, so the error looks
wrong to me.
