All I've heard about this is that some kernel changes are (still?) 
needed, then just the glibc support along w/ TLS (Maybe compiler support?).

I believe I heard reports that the glibc people were looking to 
deprecate linuxthreads within a another release or two (but don't know 
specifics or anything), so it sounds like NPTL should be something to 
get working.
