Description
Take an index with keys of near perfect uniform distribution. In the repro, I use an MD5 hash. Perform a reindex on the collection.
The next many inserts to this collection will cause all the buckets to split, which leads to the index very quickly double in size. This size is often much larger than the index was before reindexing.
The reindex command should leave the index in a state where it does not almost instantly double in size.
