func TempFileSequential(dir, prefix string) (f *os.File, err error) {
	return ioutil.TempFile(dir, prefix)
}
TempFileSequential creates a new temporary file in the directory dir
with a name beginning with prefix, opens the file for reading
and writing, and returns the resulting *os.File.
If dir is the empty string, TempFile uses the default directory
for temporary files (see os.TempDir).
Multiple programs calling TempFile simultaneously
will not choose the same file. The caller can use f.Name()
to find the pathname of the file. It is the caller's responsibility
to remove the file when no longer needed.
