Simple, reasonable, obvious rule. Avoids breaking apps that store
some bits in the top of pointers (provided that memory allocator
userspace libraries also do the right thing).
So brk would simplify fail instead of crossing the 128 TiB threshold?
glibc malloc should cope with that and switch to malloc, but this code
path is obviously less well-tested than the regular way.
Thanks,
