Should I know about these problems?

Not necessarily. An open transaction allocates more resources (both in client and server) than just locks.
But you don't need to close a transactions after each and every commit() call, if you're doing multiple commit() calls.
Think of a transaction as a JDBC connection with autoCommit==false: open, modify, commit, modify, commit, modify,
The close() of the session also closes all views/transactions.

Hmm, are the shipped implementing classes good enough? Hard to say what purpose you have in mind ;-)
