You can always do the same thing by means of conditions and signals.  The
paradigm is slightly different, though.

//...
boost::condition cond;
object1.signal.connect(boost::bind(&boost::condition::notify_all, &cond));
object2.signal.connect(boost::bind(&boost::condition::notify_all, &cond));
cond.wait(mutex_lock);
//...

In this case, the objects have explicit signals (consider the parallel to
windows kernel objects, which have an implicit "signal", i.e. their wait
state).
