6807	execute_sql in django/db/models/sql/query.py fails with MySQL due to incorrect sentinel	tpherndon	tpherndon	"Line 1333:  return iter((lambda: cursor.fetchmany(GET_ITERATOR_CHUNK_SIZE)), []) fails under MySQL because the cursor.fetchmany() call returns an empty tuple as sentinel, rather than an empty list.  The empty list sentinel is correct for sqlite.  I attempted to run runtests.py, which hung on ""Running post-sync handlers for application string_lookup"".  When I changed the sentinel to a tuple, runtests.py ran to completion (four failing tests, but completion) with MySQL, yet hung in the exact same place with sqlite.
