Problem
1. In a process may contact the owner of a page via the page manager. It may want ownership or the page itself, which are independent quantities. Do all four cases exist (excepting, of course, the case where the requester does not want the page and does not want ownership)?
2. Suppose that two variables, A and B are both located, by accident, on the same page of a page-based DSM system. However, both of them are unshared variables. Is false sharing possible?
