	  A current limitation of NEM (Non-Evict mode) is that code and data sizes
	  are derived from the requirement to not write out any modified cache line.
	  With NEM, if there is no physical memory behind the cached area,
	  the modified data will be lost and NEM results will be inconsistent.
	  ENHANCED NEM guarantees that modified data is always
	  kept in cache while clean data is replaced.
