It's not as simple as the added code wants to get a queue from the
hwctx, which we can't get at.  I was planning to look into this, but
there are various other regressions in the recent block updates that I
need to fix before I can even test a tree with this one reverted.

If you can get to sorting this out soon I'd love you to handle it,
otherwise I'll look into it as soon as I can.
