A unit test should test a single codepath through a single method. When the execution of a method passes outside of that method, into another object, and back again, you have a dependency.

I think it depends on how resources are produced and consumed. If 5 work objects are available at once and you have 5 consumer objects, it would make sense to wake up all threads using notifyAll() so each one can process 1 work object.
