db_debug=TRUE will cause transactions to not rollback or commit. [this is not documented in help]

It justs says to turn db_debug off when you want to display your own errors.... It does not mention that transactions will/may not commit or rollback if db_debug is set to TRUE.

I am mentioning it as this has caused a few people problems on the forums, and it also doesn't give confidence in the code to a newbie using transactions as they often test with an out of box solution which has db_debug on.
