+This function operates exactly as \function{TemporaryFile()} does,
+except that data is spooled in memory until the file size exceeds
+\var{max_size}, or until the file's \function{fileno()} method is
+called, at which point the contents are written to disk and operation
+proceeds as with \function{TemporaryFile()}.
+
+The resulting file has one additional method, \function{rollover()},
+which causes the file to roll over to an on-disk file regardless of
+its size.
