Myrna van Lunteren commented on DERBY-5213:
-------------------------------------------

oops, just realized I forgot to undo the changes to lang._Suite in my initial patch for this - I commented out a bunch of tests for a mini-trial run.
That's of course not intended for commit.

> An uncommitted TRUNCATE TABLE command does not block online backup. We should verify that the online and backed up databases are both in a consistent state. At a minimum, we should test the following:
> o uncommitted truncate table followed by online backup and then access the backup copy and access the table.  should see the old data.
> o uncommitred truncate table, followed by online backup that keeps logs,
>   then commit the truncate, and then access the table in the backup.
