So you need RANDMMAP exceptions to make hints respected, but that disables PaX ASLR, and a bit of vanilla ASLR is even disabled too (brk).
You could use such a lock in the implementation of mmap to work around kernels that don't implement requested-address, though.

A lock in the userspace interposition of mmap/mremap/munmap may suffice. A MAP_FIXED | MAP_NOOVERWRITE would be nice.

Yes. I'm doing similar but instead replacing default address and my current hack is not thread safe. I don't have the kernels view of VMAs.
