How to prevent 2 separate databases in the same MongoDB instance competing for RAM?

Is there a way in MongoDB to cap the RAM usage at per database in the
same MongoDB instance so that different apps can co-exist using the
same MongoDB instance? One our bigger challenges today is to maximize
the MongoDB usage so that it offers the maximum ROI. This can only be
achieved to share across multiple apps (thus different databases).
