// Cache ways 1,2,3 do not have SelFlush = 0

// To make SelFlush = 0 we must evict lines from ways 1,2,3

// Will load 4 words with same tags, filling 4 ways of cache

// edit and store these words so that dirty bit is set ( is this necessary?)

// Will then load 4 more words, evicting the previous 4 words

// will make SelFlush = 0 for all 4 ways.
