Guard pages are for the process that creates them, they're not for the other processes that try to read the memory.

Absolutely wrong. Are we writing the same code here? Page guards are for all userspace access. (In fact, I think kernel space might also trigger them, but can be circumvented. PS: I'm being polite :) Kernel space 100% triggers them, but can be cleverly circumvented by fucking with logs.)
