Known bugs/issues in this release:

* Time fields are broken in some dbdrivers. Depending on the driver, it's
  possible that the "Meeting Time" field in the sample doesn't work.

* Exception handling could be improved

* Operations on the Session Manager interface are not atomar

* Inserts that are committed at the same time are sent to the database in
  random order. This means that, in case newly inserted instances reference
  each other, the database might throw a foreign key violation.

* Appserver doesn't test referential integrity for reference fields.

* Trying to return a non RPC transportable type from a procedure (e.g. an
  object) results in a confusing exception.
