docs: Get the Handle to the last modified or added record.
  This uses some very inefficient (and incorrect) code... override if possible.
  NOTE: There is a huge concurrency problem with this logic if another person adds
  a record after you, you get the their (wrong) record, which is why you need to
  provide a solid implementation when you override this method.
  @param iHandleType The handle type.
  @return The bookmark.
