I do know about OpenMP and I seem to remember that there is an article 
about same in the FPC Wiki.

A C++ extension might use some syntax-candy (like "parallel") to make 
OpenMP (hidden in a library) easily usable.

std::async(), std::future and std::promise seems to be provide some 
"sntax candy" for making threads more usable.

here in the FAQ they write:
"The *packaged_task* type is provided to simplify launching a thread to 
execute a task. In particular, it takes care of setting up a *future* 
connected to a *promise* and to provides the wrapper code to put the 
return value or exception from the task into the *promise*."
