Review comment:
Below, `preparedClients.keySet().removeIf(c -> c.bundleRefCount.get() <=
0);` removes everything that isn't referenced. These two statements are
logically one unit and hence I prefer to not scatter them:
```
client = currentCache.getUnchecked(executableStage.getEnvironment());
client.ref();
client.ref();
```
