I guess this is my thinking: it's really not that much of a stretch to make signals behave like GetMessage(). Indeed, sigopen() brings them sufficiently close. By doing this, you DO provide this unified interface for all the different types of events you described which works much like GetMessage(). So, but adding a couple of syscalls you avoid having to implement a whole new set of API's for doing AIO, semaphores, msgqueues, etc.

P.S.: What do you mean by explicit binding between event queues and threads? I'm not sure I see what this gains you.
