started up a 2.4 replica set, and added a 2.5.3 secondary
- create an index with
{background:true}
on a large collection, on the primary
- immediately call dropIndexes()
From my understanding of how background indexing should now work in 2.5.x the background index build should be aborted when the dropIndexes command is sent. However it looks like the secondary is continuing to build the index to completion before dropping it.
