Review Comment:
   @davids5 This is what I am doing till now, but there are two problems:
   * There are limited breakpoints that the debugger can set. On more for this 
check means one less for debugging the application.
   * If for any reason you forget / remove it and the check fails, you lost the 
opportunity to diagnose the issue.
   
   Since this is not going to introduce any overhead, why not add it?
