Why not just make it private[spark] for now? Otherwise we'll have to
preserve the semantics and visibility of this function for a long time. If we
change around the way we do garbage collection. But if we make it private now
we can wait for feedback from people who want to use this (I'm still not sure
exactly what case that would be) in deciding how and what to expose.
