I just found one breakage due to this patch: `cat /proc/self/maps`
does not always get the stack marked right. I think this is because it
gets the $esp a little to early, even before the vma is sent to its
randomized space. That is why /proc/self/smaps works just ok as it
always wins the race due to the sheer volume of data it prints.
Similarly numa_maps always fails since its write volume is lower than
maps. I'll try to fix this.
