	  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.
