Re: cf-agent and memory usage

Here are the docs for the datastate() function for reference: 
https://docs.cfengine.com/docs/3.18/reference-functions-datastate.html

I would assume that the return from datastate() is quite large due to your 
policy defining many vars and classes.

Can you give a minimal reproducer of some sort or some more information 
about your policy that does something like

```
"state" data => datastate();
```

From what you said I assume you have something like that and using cf-agent 
--verbose or --debug you can see that it is "redone in pass 2"?

Could you use classesmatching to find just the classes you want and send 
those to your template?
