I remember only now, sorry, that there is another, more radical option which
we should consider if we really want to fix 11705 too: avoiding completely
the use of basic_filebuf for cin, wcin, and so on, not /only/ when
sync_with_stdio is true but also when is false:

Perhaps it's time to tackle seriously those issues??

Thanks for any help,
Paolo.
