Juda Kaleta:

We are using SQLAlchemy to pool connections to MySQL server (together with django-mysqlpool). After upgrading to 0.9.6 many error like this have started to appear frequently.

```
sqlalchemy.pool.QueuePool	Exception during reset or similar

Traceback (most recent call last):
  File "/home/mcat/venv_sk/local/lib/python2.7/site-packages/sqlalchemy/pool.py", line 557, in _finalize_fairy
    fairy._reset(pool, echo)
  File "/home/mcat/venv_sk/local/lib/python2.7/site-packages/sqlalchemy/pool.py", line 688, in _reset
    pool._dialect.do_rollback(self)
  File "/home/mcat/venv_sk/local/lib/python2.7/site-packages/sqlalchemy/pool.py", line 79, in do_rollback
    dbapi_connection.rollback()
OperationalError: (2006, 'MySQL server has gone away')
```

Recycle and other arguments passed to pool haven't changed and should be correct.
