I don't expect transactions to fail.  I try and look for problems
before running the transaction.  So the overhead of clearing the
entire index/cache shouldn't happen too often.

Under catalyst, where the croak is caught and an error is displayed.
It's odd to then make a request for showing that item again and see the
incorrect column data displayed.  Confusing because the error said
that the database couldn't be updated (e.g. due to text in an integer
column), but now it's showing that data.

Maybe others are using do_transaction in a different way?
