To pause a subgraph feeding a node, all upstream nodes would need
to be paused.  If some of those upstream nodes are also feeding
not-paused nodes, then I don't think we want to pause these
upstream nodes.  I don't know that we can have the concept of
pausing a subgraph, given the generality of graphs.

The issues are similar with an explicit pause API or with implicit
pause on disconnect.
