Return a newly‐allocated maximally‐aligned block of memory of the specified `size` (in bytes) that has a read/write protected guard page located immediately before or after it according to the `GuardPageLocation` indicated at construction. If `size` is 0, no memory is allocated and 0 is returned. Note that a multiple of the platform's memory page size is allocated for _every_ call to this method.
