Oh, that is definitly planned as part of an 'epoll' interface I have
been calling Event.
depending on the compiler, Concurrent might be implemented on top of
Event or Event might be implemented on top of Concurrent :)
In any case, I left it out of the proposal here because it is relatively
orthogonal (from a design, not an implemenatition point of view) but I
definitly think it should exist.
