Yes, it is tested. I wrote two programs: One calling io_map and mapping the memobjrd for writing, which is basically an exploit. The other creates a proxy memory object restricted to VM_PROT_READ from the memobjrd object, and then any attempts to write tot he mapped region (mapped with VM_PROT_READ|VM_PROT_WRITE) segfaults.
