Dave,

>Of course it's not thread-safe. But then there's no way to portably
construct a singleton instance on demand if two threads may demand it at
the
same time, is there?

Quite.

There is also an interesting article at
http://lib.stat.cmu.edu/~lamj/sigs/c++-report/cppr9606.c.vlissides.html by
John Vlissides, unfortunately it contains more problems than solutions -
but is probably essential reading if only to see what all the traps and
pitfalls are!
