A customer had an index build that was stuck for days or weeks. getIndexes() and the Atlas UI will show the index, leading them to believe it is available to be used.

Currently, our docs tell customers to use getIndexes() to confirm that the index was created. More importantly, we don't have a quick way to reveal that a long index build is still in progress or stuck. They can run currentOp, but that's another step to verify that indexes in the output of getIndexes() are actually ready to use.
