Leaky Functional Bucket

To combine multiple calls to one function into one call (after all others are finished), use setTimeout to break out of the current call stack!

function collector() {
  collector._count = collector._count || 0;
  if (!collector._count) {
    setTimeout(function() {
      target();
      collector._count=0;
    }, 0);
  }
  collector._count++;
}
