Hello everyone! Could you tell me if FreeBSD supports memory page nulling when releasing it to prevent unauthorized access to data left in the page after it's allocated again. If it does, what sys calls etc provide that? IMHO this is an important issue when operating data with different sensivity levels. Thanks in advance. Nick
