Ok, this makes sense.  Each passenger thread needs to know about the
queue, because that's the place you want the passenger to drop out of.

Lists support a 'remove()' method, so you may be able to use it.

Yes.

This is usually unnecessary, as the same garbage collection that recycles
the class does the same to attributes of the class.
