I did try an m1.xlarge with 1000 agents connected (across 10 actual
machines). And then I added nrpe-external-master and added the relation.

We pretty steadily hit >200% CPU (often up over 300%). And then I saw
memory grow over 14GB and the process was killed by the OOM killer.

So something about having a subordinate is spiking memory enough that
it is killing jujud, even with only 1000 units.

Definitely something I think we'll want to investigate more closely.
