Instead, the opposite was chosen: each workload will list the policies that select it.
This works out to be more efficient in common cases where policies change much less often than workloads.
This only applies for selector-based policies; namespaced and global policies can be handled without needing to list them out in the Workload API.

## Memory

If you run **a single process per container** you will have a more or less well-defined, stable, and limited amount of memory consumed by each of those containers (more than one if they are replicated).
