Thanks for your replies.

To me boost::condition looks very much like the old event variable, except that it works together with a mutex. I am now wondering why you should lock a mutex before waiting for the condition? Is there a rationale about this?

Also note that the wait() on the condition unlocks the mutex until you return from the wait call. That's not always obvious from the examples.
