Small comment on this patch: The class name in the header boilerplate does not
agree with the actual package and classname of the file.

> When a Derby instance has the master role for a database, log records are
> shipped to the slave to keep it up to date. A buffer is needed because the
> log records should not be shipped one at a time. Also, writing the log
> records to a buffer instead of sending them immediately removes the network
> communication from the critical path for the transaction.
