Summary: This class was initially in Host because its implementation used to be very OS-specific. However, with C++11, it has become a very simple std::condition_variable wrapper, with no host-specific code. It is also a general purpose utility class, so it makes sense for it to live in a place where it can be used by everyone. This has no effect on the layering right now, but it enables me to later move the Listener+Broadcaster+Event combo to a lower layer, which is important, as these are used in a lot of places (notably for launching a process in Host code).
