Sorry, but this one isn't really negotiable for so many reasons.

Not really, and more importantly I don't see how it would be relevant to 
using a main() wrapper any way.

Yes, I understand that.  Thus I *have* to abide by the rules of the 
underlying thread library when I can (and as C libraries they are mute on 
this subject) and by the C++ standard when I can't.

You can question it when you are defining the standard, not when building a 
library such as Boost.Threads.  There all that you can do is, again, to 
follow the rules of the underlying thread libraries when they are defined, 
and the standard when they are not.

Only when you can do so, which means the underlying libraries must define 
the behavior.  If they do not, then I must obey the defined behavior of the 
language.
