Persistence stops at the machine boundary. The difficulties of network recovery after a crash are no better or worse than for any other system. Yes, there exists a mechanism that allows certain applications to demand a checkpoint now. This mechanism is considered sensitive, and it is NOT available to applications in general. It is used by things like database systems and system installers. shap _______________________________________________ L4-hurd mailing list [email protected] http://lists.gnu.org/mailman/listinfo/l4-hurd
