Re: [boost] Re: TR2 and C++0x heads up

I dont know if this thread is the best place to make this question, but...
Where do I find the proposals about threads in C++? libs, core
language modifications, memory model and etc... ? And I've seen
somewhere that there's some group discussing about those things
either, but I had only access to it through a page... maybe there's
somehow for others to receive those mails? Even havent permission to
reply any? I'm really interested about it, but I fear things like
atomicity garantees to volatile and static variables and some others
too strong garantees...

Thanks in advance
