// reset by the sc_signal<bool> whose interface has been supplied. If no
// sc_reset object instance has been attached to the sc_signal<bool> yet, it
// will be created and attached. The active process instance is pushed into
// the list of processes that the sc_reset object instance should notify if
// the value of the reset signal changes.
//
// Arguments:
// async = true if the reset signal is asynchronous, false if not.
// iface = interface for the reset signal.
// level = is the level at which reset is active, either true or false.
// Notes:
// (1) If reset is asserted we tell the process that it is in reset
// initially.
