+A half-sentence in mmc5r03c.pdf 6.3.3.3.3 might indicate that closing a session
+by 5Bh CLOSE TRACK SESSION Close Function 010b overrides the multi-session bits
+in mode page 5.
+growisofs applies this function in case of not DAO, though. A comment in
+growisofs_mmc.cpp states: "// DVD-R DL Seq has no notion of multi-session".
+I am not reading this from the specs - but not explicitely the contrary either.

+For now libburn will close the session but there is a macro prepared in
+libburn/write.c Libburn_dvd_r_dl_multi_no_close_sessioN which will suppress
+close session if multi-session is demanded.
