--TEST--
PHPC-1050: Command cursor should not invoke getMore at execution (rewind omitted)

/* Note: this test is skipped on PHP 8 because the InternalIterator class
 * returned by Cursor::getIterator() has logic to ensure rewind() is always
 * called. That causes and additional getMore to be observed when starting
 * iteration with next(), since rewind() and next() both trigger a getMore.
 * We may be able to resume running this test on PHP 8 if Cursor implements
 * Iterator directly and allow rewind() to be optional (see: PHPC-1691). */
