BTW I kind of prefer this solution over the alternative one, at least for
now. The very best solution would be to broadcast the part of the task
description that's shared across tasks to all nodes. Otherwise putting these in
the block store will lead to lots of replicated data. But it's better to warn
for now and maybe tell them to use broadcast.
