If I were feeling paranoid I might be tempted to not only keep the pool exported when not in use, but to 'zpool offline' one half of the mirror while performing the receive, then put it back online and allow it to resilver before exporting the whole pool again. I'm not sure if there's any way to wait for the resilver to finish except to poll 'zpool status', though.
