There's nothing different about GC within lambdas.  You simply need to
be aware of how lambdas work.

The lambda object needs to maintain references to everything that was
visible within the scope where it was created.  As long as the lambda
object is alive, everything it references must also stay alive.

If you allow the lambda object to be garbage-collected, the things it
references will also be subject to garbage collection. =20
