As with anything, you can set them to null just to be safe - if you do
that, the GC *may* get them sooner than if you don't.

If you don't set them to null, they'll remain referenced by the
containing object and not be collectible until the containing objects
are destroyed by the GC, which is kind of indeterminable. :-)
