Nice problem we ran into there :-)
I would actually think it would be best to implement both options; 1)
because it'll definitely solve the problem and makes us compatible with
BeOS - we could make the change a compiler option - and 2) because it's
more elegant, anyway :-)
Also, what about the thread safety problem in the initialization? Is
that easily solvable? And if not, what could happen in the worst case?
