Review comment:
Should the markPool check should be done regardless of if something was
thrown or not. Some throws are expected and allowed (e.g Runtime SDE) and we
need to make sure the markPools are cleaned up appropriately in this case so
successive parses don't fail. The other ones like stacks are less important
since the PState is thrown away, but mark pool persist between parses and leaks
cause real issues.
