This next pass won't be until thirty seconds later, so it'll take about half an hour to completely obliterate a file. Furthermore, unmounting a file system less than half an hour after a file is deleted or truncated will fail, and shutting down will most likely leave the file system unclean due to repeated failures to flush the dirty buffer list.
