Comment 10 for bug 997460

The problem was that in MySQL 5.5 the old code for handling truncate by delete-row-one-by-one was removed()
This was used in Aria for the case when one didn't have auto-commit and we wanted to be able to rollback a TRUNCATE.

Have now fixed this by forcing the Aria internal truncate call to do an explicit commit.
The disadvantage is that we can't rollback TRUNCATE anymore in Aria.
