Comment(by tomeu):

 Replying to [comment:3 sascha_silbe]:
 > > But in order to be deterministic, you also need to have the same data
 and metadata, having the same index is not enough. So, why not just delete
 the whole DS, then adding entries with Create?
 > That's exactly what I'm doing. The test suite creates a temporary
 directory and starts up a new datastore instance with HOME set to the
 temporary directory. But since an empty directory doesn't contain an
 index, the datastore will schedule an index (re)build. I need to wait for
 the index build to finish, otherwise API calls like get_uniquevalues() or
 find() won't work properly.

 Right, but I was suggesting creating the index cia create() calls, instead
 of reindexing the whole directory. Is this so impractical for your use
 case to warrant new API?
