More bits doesn't eliminate the need to context switching unless you adopt a "single address space" model. There is lots of work on that. Try a google search for "SASOS" and/or "single address space operating system". Adopting a single address space view is a religious issue. shap _______________________________________________ L4-hurd mailing list [email protected] http://lists.gnu.org/mailman/listinfo/l4-hurd
