Recently I'd switched to SA MySQL connection pool implementation.
Every time, when app returns connection to pool (through .close()
method), SA triggers .rollback() on this connection (http://
www.sqlalchemy.org/trac/browser/sqlalchemy/trunk/lib/sqlalchemy/pool.py#L291).
In my case ROLLBACK is rather expensive operation and waste too much
MySQL time. I'm using MySQL 5.1 and "set autocommit=1" on
initialization.

How to disable this .rollback() triggering?
