title: Is int safe to read from multiple threads?
body: <p>I have multiple threads reading same int variable. 
  and one thread is writing the value. </p>
  
  <p>I don't care about the race condition. </p>
  
  <p>only my concern is writing and reading int value at same time is memory safe ?</p>
  
  <p>and it will not result in any application crash . </p>
