Crashing is typically better than silently failing, because it makes it easier
to find and fix the issue; I'd remove this check.

Alternatively, you could make selector always be a function by doing something
like this before the doWait definition:

  if (typeof selector == 'string) {
    var id = selector;
    selector = function() { return $(id) };
  }
