	`If the TLB hardware detects no matching entry on a "tbs" instruction,`
	`it does an "or" of the MSB into the index register, in contrast to`
	`the simulator, which sets the bit (and clears the bit if a matching`
	`entry is found). In this way the MSB was never cleared automatically,`
	`which led to strange behavior in the NetBSD kernel. Solved in favor`
	`of the simulator.`
