        Precisely. Without a library, we can't see what it is
that is really needed in the language core.  Without changes
in the language core, we can't have the library.

        It is probably reasonable to supply a faulty
implementation with a note that it may fail on system X
occasionally: that may put pressure on system X's vendors
to fix the problem so it will comply in advance with a possible
future C++ Standard. After all, technically, all bets are
off when you're multithreading anyhow. :-)
