Review Comment:
You have just said it yourself. Old code for `shouldDiscard=false` is doing:
```
try {
cleanupAction.run();
} catch (...) {
...
} finally {
decrementNumberOfCheckpointsToClean();
postCleanupAction.run();
}
```
with no exception and the `cleanupAction` being `NOOP`, code simplifies to:
```
decrementNumberOfCheckpointsToClean();
postCleanupAction.run();
```
`decrementNumberOfCheckpointsToClean` is clearly there.
