When the memory allocator reserves virtual addresses, it still does not know what they will be used for. Besides, huge areas are reserved for memory hotplug in multiprocess setups. But most of the pages are unused in the whole life of the processes. Change protection mode to PROT_NONE when only reserving VA. The memory allocator already switches to the right mode when making use of it. It also has the nice effect of getting those pages skipped by the kernel when calling mlockall() or when a coredump gets generated.
