The applyOps command currently takes out a global exclusive lock and applies operations serially. This limits the number of operations that can be applied due to the lack of concurrency. Having applyOps (when in non-atomic mode) not take out a global lock would allow us to parallelize applyOps calls and take advantage of collection- and document-level locking.
