threading locks. The python logging module happens to use such locks. To

a ROLLBACK. Database Errors like IntegrityError will be raised in
session's __exit__ handler, and any try/except within the context managed
by session will not be triggered. And catching other non-database errors in
the session will not trigger the ROLLBACK, so exception handlers should
always be outside the session, unless the developer wants to do a partial
commit on purpose. If the connection is dropped before this is possible,
the database will implicitly roll back the transaction.

Note: update_bar is a trivially simple example of using "with session.begin".
Whereas create_many_foo is a good example of when a transaction is needed,
it is always best to use as few queries as possible. The two queries in
update_bar can be better expressed using a single query which avoids
the need for an explicit transaction. It can be expressed like so:
