Description
We moved the parsing of the aggregation pipeline to within the collection lock as part of SERVER-25038. On storage engines that support document-level locking, this isn't likely to be a problem, since the lock will only be an intent lock. On storage engines like MMAPv1, there may be some noticeable overhead, which we should investigate and maybe attempt to mitigate.
