In this direct approach I presume you need to somehow derive from (or make a
copy of) QEventLoop and put the relevant magic in there.
I also presume that QProcess takes care of all that one way or another, so
maybe ForkedcallsController could just use QProcess instead if on Qt? That
would make life simpler methinks.
