title: Why it's termed read-modify-write but not read-write?
body: <p>In my opinion, the term <em>read-modify-write</em> doesn't make much sense, since <em>modify</em> is just another way of saying <em>write</em>. Quoted from <a href="https://en.wikipedia.org/wiki/Read-modify-write" rel="noreferrer">wikipedia</a> (emphasis mine):</p>
  
  <blockquote>
    <p>In computer science, read-modify-write is a class of atomic operations
    [...] that <strong>both read a memory location and write a new value into
    it simultaneously</strong> [...]</p>
  </blockquote>
  
  <p>So why not simply read-write? Any delicate semantic difference between the two? </p>
