Our usage of pthread conditions does not allow a single thread to wait for several events from different sources. This is because the condition is bound to the source of the event. We can invert the usage by giving each thread its own condition and providing APIs for registering this thread condition with several sources. Each of the sources can then signal the thread condition.
Thread queues also support several threads to be registered with a single event source, which can either wakeup all waiting threads or just the first one.

ACK, I don't see anything wrong with this but let's see how it's used. Peter
