Facing issue by using yield_per

See original GitHub issue

DB: mysql:5.7.0

instances = session.query(Model.id, Model.some_value).yield_per(magic_number).enable_eagerloads(false)

Base on diff magic_number such as 81 or 101 and so on, will raise.

Traceback (most recent call last):
  File "sqlalchemy_py/sqlalchemy/engine/base.py", line 1193, in _execute_context
    context)
  File "sqlalchemy_py/sqlalchemy/engine/default.py", line 507, in do_execute
    cursor.execute(statement, parameters)
  File "/usr/lib/python3/dist-packages/MySQLdb/cursors.py", line 189, in execute
    while self.nextset():
  File "/usr/lib/python3/dist-packages/MySQLdb/cursors.py", line 142, in nextset
    nr = db.next_result()
_mysql_exceptions.ProgrammingError: (2014, "Commands out of sync; you can't run this command now")

any idea? thanks.
