@HeartSaVioR
Thanks for taking a look. Well, I was trying to follow his comments. :)
I noticed though, that the line in my `let` binding
```Clojure
valid-node+ports (vals task->node+port)
```
maybe should have been
```Clojure
valid-node+ports (vals @task->node+port)
```
with the `@`.
`task->node+port` is actually an atom, however, so if we dereference it
within the read-lock there, we should have the accurate task assignment before
we add anything to the queue to be sent. I believe this addresses the concern
you cited from @nathanmarz. The other change was to encapsulate the separate
TransferDrainer#add, since it does not need to be a separate public method.
So, @HeartSaVioR, since we have both looked at my branch already, do you
want to take my changes into your branch and continue the discussion from
there? It seems like a smaller set of changes to begin with, and maybe it
would be easier going forward?
