POSIX provides pthread_once. We should use it. The Windows Vista functions look to supply a similar facility, and do at least allow the passing of a parameter to the routine without using TSS.

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).
