I'm confused. It sounded like Ognyan was saying that the page is still assigned to the same area. But it is necessary to vm_free when the kernel tells you to page out. It is unfriendly (and very bad for performance) to hold on to the page. _______________________________________________ Bug-hurd mailing list [EMAIL PROTECTED] http://lists.gnu.org/mailman/listinfo/bug-hurd
