Original commit message:

    [heap] Ensure progress in unmapping memory chunks.

    If sweeping is not making progress and there are many young generation
    GCs happening, then this can lead to accumulation of memory chunks in
    the unmapper queue.

I'm leaning towards squashing when I land it (incrementing the version string only by one). Thoughts?
