I think we can safely assume that the total physical memory does not change between two calls.
CHECK_MARGIN(info.PageSize, sys_basic_info.PageSize);
The pagesize should usually also match exactly.

A tolerance of 64 (especially for process/threads) basically disables these tests. A smaller tolerance would already be sufficient to avoid random test failures.
