Um, possibly not, if you're using connection-pooling software ... and
even if you're not, I think closing the connection is asynchronous;
it'd be possible to establish a new connection before the old one has
terminated and released its locks.
Rather than closing the connection, I think you need to do something
explicit to commit your transaction.
