Any particular thoughts as to how large a window should be reserved? SHLIB_BASE is a bit more than 1MB, which is fairly small in the grand scheme of things, but I guess I don't see why you'd reserve more than PAGE_SIZE (or maybe PAGE_SIZE*2, though I can't actually articulate why that seems like a good idea).
You also want to catch not-quite-NULL pointer dereferences, where you dereference the member of a large struct or array, but the array or struct pointer itself was NULL.
Eg. you try to fetch the 100,000th from an array, but you got passed a NULL array pointer. Getting a segfault is much, much better than corrupting data.
