rolls back. If the conflicting transaction is say waiting for a user
to click something on a dialog and that user is out at lunch, then the
you will be waiting an awful long time.
There is development in the pipeline to allow you define a timeout for
the WAIT, but for now you need to either ensure your transactions that
hold those locks are not running for extended periods of time, or you
need to change to NO-WAIT transactions and put wait-then-retry logic
into your application.
