I just realized to my surprise that c++0x standard won't include
thread barriers (not to be confused with memory barriers). boost had
thread barriers for a long time and I kinda assumed that the standard
will too.
Were thread barriers ever considered for inclusion?
And if yes, why were they removed?

I understand that you can achieve the same effect by using other
primitives like condvars, but the solution with barriers was so simple
and elegant...

Thanks,
  Andy.
