 Description   

As part of SERVER-37085, one of the noticeable changes in $out performance resulted from switching off of the DBDirectClient to use write ops directly. Note that if we did decide to "backport" this, it would have to be a custom fix since the original change was part of SERVER-35895.

We haven't heard any complaints about the performance of $out on existing versions, so we're declining this request.
