- Make rnd hints avoid the brk area. The rnd allocator refuses to allocate in
the brk area anyway.
- Use a larger hint bound to spread the allocations more for the 32-bit case
- Simplified the overy abstracted brs/stack allocator and switch of
guard pages for the brk case. This allows i386 some extra space,
depending on memory usage patterns.
- Reduce brk area on i386 to give the rnd space more room
