Allocate and lock memory pages.
If len is not a multiple of the system page size, it is rounded up. Returns 0 in case of allocation failure.
If locking the memory pages could not be accomplished it will still return the memory, however the lockingSuccess flag will be false. lockingSuccess is undefined if the allocation fails.
Implements LockedPageAllocator.
