At the end of the day, backpressure means that you limit the rate at
which you launch the dependee tasks (the A and B tasks). You can do
this two ways. Have the dependent task responsible for launching its
dependencies every time it completes, and some condition is met (for
example, that there are less than N dependent tasks active). Or, the
dependee task blocks until some condition is met (again, when there
are less than N dependent tasks active).

There is no need to resort to exotic libraries or operating system
facilities, this is a straightforward problem which can be solved
entirely using the C++11 standard library.

Thanks
