/**
 * reindex_background.js
 *
 * Bulk inserts 1000 documents and builds indexes in background, then alternates between reindexing
 * and querying against the collection. Operates on a separate collection for each thread. Note
 * that because indexes are initially built in the background, reindexing is also done in the
 * background.
