Before we were waiting on iputs after we committed the transaction, but
this doesn't really make much sense.  We want to reclaim any space we
may have in order to be more likely to commit the transaction, due to
pinned space being added by running the delayed iputs.  Fix this by
making delayed iputs run before committing the transaction.
