> {{SplitDocumentCleanup}} currently iterates twice over {{splitDocGarbage}}.
> NOTE: not the case for Mongo DB, as {{MongoVersionGCSupport}} overwrites
> {{deleteSplitDocuments()}}.
> {{deleteSplitDocuments()}} currently iterates over {{splitDocGarbage}} to
> obtain the IDs of the documents to be deleted. Instead, we could just collect
> the IDs inside {{disconnect()}}, the memory requirements would be the same.
