It is a part of Boost.Move library
http://www.boost.org/doc/libs/1_48_0/doc/html/boost/forward.html
. Works like std::forward, when there are rvalues, otherwise tries to
emulate them.

May be you are right. I`ve proposed it, because it potentially can
give some better results in error detections (For example you switch
contexts, do some work, than switch back. There is a small chance,
that some data/register was not stored in context and was not changed
between context switches. When you move context to another thread,
there is almost no chance that data/register in different threads will
match, so there will be easier to detect error/unstored data.)
