Makes sure setTimeout waits long enough.

ensureSetTimeout.js

function ensureSetTimeout(cb, s) {
  var callTime = Date.now();
  setTimeout(function() {
    var cbTime = Date.now();
    
    if(cbTime - s == callTime)
      cb();
    else
      ensureSetTimeout(cb, s - (cbTime - callTime))
  }, s);
}

exports.ensureSetTimeout = ensureSetTimeout;
