Am I correct to assume that something like this would already be implemented in a mongodb wrapper/lib? A quick examination of mongojs (https://github.com/gett/mongojs/ https://github.com/gett/mongojs/), the wrapper I'm using now, would suggest so. Also, I thought the 'official' mongodb library already does connection pooling, or is this something different? Just curious.
