Nearly. It was:

	sync; sync; sync; <hit big red power button> :-)

The only reason to run sync 3 times was because the command exited
before the data could be guaranteed to be flushed to disk. The logic
was that by the time the third one exited, the first one would have
been able to finish flushing to disk.
