The UnitOfWork implementation is part of the user supplied code. This is to allow the maximum flexibility for many different use cases. NHibernate is a tool and the tool has to be employed following the instructions. Every single write to the database cannot be wrapped in a transaction, as there are times those writes need to be batched or grouped with other writes.
You as the application developer need to take some responsibility.
