/**
* Helper that simply does an RPC. It can be used similar to a sleep for negative testing: to give
* time for actions _not_ to happen. Since it is based on doing an actual RPC with actual
* callbacks, it generally provides plenty of time for Runnables to execute. But it is also faster
* on faster machines and more reliable on slower machines.
