No. read_timeout feature was added to MySQLdb only in 1.2.5. If you're using Ubuntu, you'll need to update python-sqlalchemy as well or else the option will be rejected in the MySQL connection string. It could be backported to 4.0, but there are no repo tools for Ubuntu on Fuel master node to do an in-place upgrade.
