did you catch my comments on this one (elsewhere in this thread)?

<cite>
   The pthread-based implementation seems overly simplified: It won't
   compile for C++ functions that are not 'extern "C"' with some
   compilers.
   Further, what about exceptions from within pthread_once?
</cite>

I agree that TSS is not a good alternative, however (but I don't think 
it's needed for an improved pthread-based implementation).
