Something that doesn't require deterministicly named tempfiles was Ted
T'so's explanation linked to earlier.

read data from important file
modify data
create tempfile
write data to tempfile
*sync tempfile to disk*
mv tempfile to filename of important file

The sync is necessary to ensure that the data is written to the disk
before the old file overwrites the new filename.
