> If they are not used when recovering you can get intro problems with duplicate output data when a failure occurs after a savepoint was taken but before the next checkpoint occurs.
> The fix, in the long run, is to differentiate between savepoints that have side effects and those that don't. The former would be used for a "stop-with-savepoint" scenario while the latter is for in-between savepoints. This is harder to implement, so I vote for the easy fix described for now for fixing the duplication problems.
